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.

The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students.

The properties and nature of water clusters studied with novel spectroscopic approaches are presented in this thesis. Following a general introduction on the chemistry of water and water clusters, detailed descriptions of the experiments and analyses are given. All the experimental results, including first size-selective spectra of large clusters consisting of 200 water molecules, are presented with corresponding analyses. Hitherto unidentified hydrogen bond network structures, dynamics, and reactivity of various water clusters have been characterized at the molecular level. The main targets of this book are physical chemists and chemical physicists who are interested in water chemistry or cluster chemistry.

Optical spectroscopy combined with mass spectrometry provides a unique opportunity to probe the intrinsic properties of biologically-relevant ions in the gas phase, free from the interfering effects of solvent interactions in the condensed phase. Electrospray ionization allows large biomolecules to be transferred intact into the gas phase for mass analysis. Modern mass spectrometers provide excellent sensitivity, mass-resolution and can efficiently isolate a single ionic species from a complex mixture. However, the extent to which biomolecules retain their solution-phase conformations in the gas phase is largely unknown. Therefore, there is considerable interest in applying spectroscopic methods to biological ions in vacuuo. Due to the low number densities of ions in storage devices, traditional absorption measurements are not feasible, requiring more sensitive analytical methods. Two such techniques are laser-inducedfluorescence (LIF) and photo-dissociation (PD) action spectroscopy, both of which measure the consequence of absorption. The work in this dissertation describes applications of optical spectroscopic methods to interrogate mass-selected ions using a variety of ion storage apparatus including a Fourier transform ion cyclotron resonance mass spectrometer, a quadrupole ion trap and an electrostatic ion storage ring. First, the conformations of small cationized arginine complexes have been investigated using infrared multiple-photon dissociation (IRMPD) action spectroscopy in the IR fingerprint region of the spectrum (200-1800 cm-1). Second, an apparatus incorporating a quadrupole ion trap has been constructed in our laboratory to perform LIF and PD-action spectroscopy. The gas-phase fluorescence and photodissociation properties of three Rhodamine dyes have been investigated including fluorescence excitation and dispersed fluorescence spectra. Finally, the latter chapters describe the use of electronic action spectroscopy to investigate a model chromophore o.
