Download Physical Chemistry of Cold Gas-Phase Functional Molecules and Clusters Book in PDF, ePub and Kindle
This book describes advanced research on the structures and photochemical properties of polyatomic molecules and molecular clusters having various functionalities under cold gas-phase conditions. Target molecules are crown ethers, polypeptides, large size protonated clusters, metal clusters, and other complex polyatomic molecules of special interest. A variety of advanced frequency and time-domain laser spectroscopic methods are applied. The book begins with the principle of an experimental setup for cold gas-phase molecules and various laser spectroscopic methods, followed by chapters on investigation of specific molecular systems. Through a molecular-level approach and analysis by quantum chemical calculation, it is possible to learn how atomic and molecular-level interactions (van der Waals, hydrogen-bonding, and others) control the specific properties of molecules and clusters. Those properties include molecular recognition, induced fitting, chirality, proton and hydrogen transfer, isomerization, and catalytic reaction. The information will be applicable to the design of new types of functional molecules and nanoparticles in the broad area that includes applied chemistry, drug delivery systems, and catalysts.

Download Noble Gas Chemistry Book in PDF, ePub and Kindle
Authored by one of the world's leading experts in the chemistry of lighter noble gases, this comprehensive monograph fills the need for an up-to-date review of the diverse experimental techniques and theoretical methods currently in practice. After reviewing the experiments breaking the paradigm of "non-reactive" noble gases, the physico-chemical background is introduced. Besides the emphasis on gas phase reactions, the author presents other relevant systems, such as chemistry in the bulk phase, under high pressure, and cold matrices. The discussion of gas-phase chemistry of the noble gases covers neutral and ionic compounds, diatomic molecules, complexes with small molecules and metal compounds, up to large clusters.

Download Structure and Properties of Atomic Nanoclusters Book in PDF, ePub and Kindle
Atomic clusters are aggregates of atoms containing a few to several thousand atoms. Due to the small size of these pieces of matter, the properties of atomic clusters in general are different from those of the corresponding material in the macroscopic bulk phase. This monograph presents the main developments of atomic clusters and the current status of the field. The book treats different types of clusters with very different properties: clusters in which the atoms or molecules are tied by weak van der Waals interactions, metallic clusters, clusters of ionic materials, and network clusters made of typical covalent elements. It includes methods of experimental cluster synthesis as well as the structural, electronic, thermodynamic and magnetic properties of clusters, covering both experiments and the theoretical work that has led to our present understanding of the different properties of clusters. The question of assembling nanoclusters to form solids with new properties is also considered. Having an adequate knowledge of the properties of clusters can be of great help to any scientist working with objects of nanometric size. On the other hand, nanoclusters are themselves potentially important in fields like catalysis and nanomedicine.

Download Manipulation of Matrix-Isolated Molecules and Molecular Clusters with Electrostatic Fields Book in PDF, ePub and Kindle
This book describes the manipulation of molecular properties, such as orientation, structure, and dynamics, of small molecules and molecular clusters isolated in cold inert matrices by using unprecedentedly strong external electrostatic fields. Manipulation of molecules with controllable external forces is a dream of chemists. Molecules are inherently quantum-mechanical systems, control of which potentially can lead to quantum technology, such as quantum sensing and computing. This book demonstrates a combination of the ice film nanocapacitor method and the matrix isolation technique enabled the application of intense external dc electric fields across the isolated molecules and molecular clusters. Changes in molecular states induced by fields were monitored by means of vibrational spectroscopy. Also, the book presents manipulations of the inversion tunneling dynamics of ammonia molecule and the dislocation of acidic proton in hydrogen chloride–water complex. The book shows that the vibrational spectroscopy with the aid of unprecedentedly strong dc electric field can provide rich information on the electrostatic behaviors of molecules and molecular clusters, which underlie the understanding of intermolecular processes and molecular manipulation.

Download Low Temperatures And Cold Molecules Book in PDF, ePub and Kindle
New, unexpected and largely unexplored physical phenomena occur in systems cooled to very low temperatures. The background temperature in the universe is approximately 2.7 K, but much lower temperatures have now been obtained in the laboratory. This book reviews the progress in a number of related fields in which the common themes are low temperatures and molecules, not atoms.This book brings together, for the first time, the results of recent research in areas ranging from the chemistry of cold interstellar clouds (10-20 K), through laboratory studies of the spectroscopy and kinetics of ions, radicals and molecules, to studies of molecules in liquid helium droplets, to attempts to create molecular (as distinct from atomic) Bose-Einstein condensates.The chapters fall into two parts, the first one dealing with low-temperature experiments and environments (ca. 1-20 K). In the context of this book, these chapters can be said to deal with relatively mature fields. The second part deals with very low temperatures and very cold molecules. Here, more emphasis is placed on the methods employed to generate samples of molecules at extremely low (1 K) temperatures.

Download An Introduction to Cold and Ultracold Chemistry Book in PDF, ePub and Kindle
This book provides advanced undergraduate and graduate students with an overview of the fundamentals of cold and ultracold chemistry. Beginning with definitions of what cold and ultracold temperatures mean in chemistry, the book then takes the student through the essentials of scattering theory (classical and quantum mechanical), light-matter interaction, reaction dynamics and Rydberg physics. The author aims to show the reader the richness of the topic while motivating students to understand the fundamentals of these intriguing reactions and underlying connecting relationships. Including material which was previously only found in specialized review articles, this book provides students working in the fields of ultracold gases, chemical physics and physical chemistry with the tools they need to immerse themselves in the realm of cold and ultracold chemistry. This book opens up the exciting chemical laws which govern chemistry at low temperatures to the next generation of researchers.

Download Physics and Chemistry of Small Clusters Book in PDF, ePub and Kindle
Recent advances in experimental techniques now enable researchers to produce in a laboratory clusters of atoms of desired composition from any of the elements of the periodic table. This has created a new area of research into novel materials since clusters cannot be regarded either as a "large" molecule or as a fragment of the bulk. Both experimental and theoretical studies are revealing unusual properties that are not ob served in solid state environments. The structures of micro-clusters are found to be significantly distorted from the most symmetric arrangement, some even exhibiting pentagonal symmetry commonly found in icosahedric structures. The unusual stability of certain clusters, now described as "magic number species", shows striking similarities with the nuclear shell structure. The relative stabilities of clusters depend not only on the composition of the clusters but also on their charged states. The studies on spontaneous fragmentation of mUltiply charged clusters, commonly referred to as Coulomb explosion, illustrate the role of electronic bonding mechanisms on stability of clusters. The effect of foreign atoms on geometry and stability of clusters and the interaction of gas atoms with clusters are showing promise for an indepth understanding of chemisorption and catalysis. The magnetic and optical properties are dependent not only on cluster size but also on its geometry. These findings have the potential for aiding industry in the area of micro-electronics and catalysis.

Download Encyclopedia of Chemical Physics and Physical Chemistry Book in PDF, ePub and Kindle
The Encyclopedia of Physical Chemistry and Chemical Physics introduces possibly unfamiliar areas, explains important experimental and computational techniques, and describes modern endeavors. The encyclopedia quickly provides the basics, defines the scope of each subdiscipline, and indicates where to go for a more complete and detailed explanation. Particular attention has been paid to symbols and abbreviations to make this a user-friendly encyclopedia. Care has been taken to ensure that the reading level is suitable for the trained chemist or physicist. The encyclopedia is divided in three major sections: FUNDAMENTALS: the mechanics of atoms and molecules and their interactions, the macroscopic and statistical description of systems at equilibrium, and the basic ways of treating reacting systems. The contributions in this section assume a somewhat less sophisticated audience than the two subsequent sections. At least a portion of each article inevitably covers material that might also be found in a modern, undergraduate physical chemistry text. METHODS: the instrumentation and fundamental theory employed in the major spectroscopic techniques, the experimental means for characterizing materials, the instrumentation and basic theory employed in the study of chemical kinetics, and the computational techniques used to predict the static and dynamic properties of materials. APPLICATIONS: specific topics of current interest and intensive research. For the practicing physicist or chemist, this encyclopedia is the place to start when confronted with a new problem or when the techniques of an unfamiliar area might be exploited. For a graduate student in chemistry or physics, the encyclopedia gives a synopsis of the basics and an overview of the range of activities in which physical principles are applied to chemical problems. It will lead any of these groups to the salient points of a new field as rapidly as possible and gives pointers as to where to read about the topic in more detail.
