Despite the existence of many competitive analytical techniques, molecular absorption spectrophotometry still remains very popular in practice, particularly in biochemical, clinical, organic, agricultural, food and environmental analyses. This is due mainly to the inherent ease and relative simplicity of spectrophotometric procedures and the availability of reliable and highly-automated instruments. Moreover, the method and its instrumentation has recently undergone considerable development resulting in some new special approaches of spectrophotometry in the ultraviolet (UV) and visible (VIS) regions.Although there are a number of comprehensive textbooks dealing with UV/VIS spectrophotometry, they tend to describe historical aspects or contain collections of detailed procedures for the determination of analytes and do not reflect sufficiently the present state of the method and stage of development reached. This book provides a concise survey of the actual state-of-the-art of UV/VIS spectrophotometry.Special attention has been paid to problems with the Bouguer-Lambert-Beer law, absorption spectra, present trends in instrumentation, errors in spectrophotometry, evaluation of analyte concentration and calibration, optimization procedures, multicomponent analysis, differential spectrophotometries, problem of blanks, derivative and dual-wavelength spectrophotometry, spectrophotometric titration, the strong relations between complex formation and spectrophotometry, spectrophotometric investigation of complex equilibria and stoichiometry or automation in spectrophotometry. The significance of spectrophotometry in connection with liquid-liquid extraction, reaction kinetics, trace analysis, environmental and clinical analysis is also covered.The text is supported by tables and figures, and numerous references are provided for each topic treated. The book is written for all those who use UV/VIS spectrophotometry in the laboratory and will also be useful to students as supplementary reading.

The inspiration for this volume lies in Edisbury's Practical Hints for Absorption Spectrometry which was published 17 years ago. Dr Edisbury was a founding member of the Photoelectric Spectrometry Group, served as its first Secretary and edited the Bulletin for many years. His wisdom, humour and pragmatism was evident in early meetings of the Group and in the first issues of the Bulletin, and these qualities were distilled in the writing of Practical Hints. In 1977, the Committee of the Group, which by then had been re-named The UV Spectrometry Group, decided to make use of the expertise available amongst the members of the Group in writing some monographs on the practice of UV and visible spectrometry. Working parties were set up which formulated and produced the first two volumes of the series on Standards in Absorption Spectrometry and Standards in Fluorescence Spectrometry. The success of these volumes lead the present Committee of the Group to set up a new Working Party in 1981 to plan a modern version of Edisbury's book. The idea really caught fire' at the first meeting of the Working Party, when ideas sufficient to fill ten vol umes were put forward. We would not pretend to emulate Edisbury's unique style, but hoped to produce a readable book for the newcomer to UV -visible absorption spectrometry, and perhaps to improve the technique of more experienced users.

UV-VIS spectroscopy is one of the oldest methods in molecular spectroscopy. The definitive formulation of the Bouguer-Lambert Beer law in 1852 created the basis for the quantitative evaluation of absorption measurements at an early date. This led firstly to colorimetry, then to photometry and finally to spectrophotometry. This evolution ran parallel with the development of detectors for measuring light intensities, i.e. from the human eye via the photo element and photocell, to the photomultiplier and from the photo graphic plate to the present silicon-diode detector both of which allow simultaneous measurement of the complete spectrum. With the development of quantum chemistry, increasing atten tion was paid to the correlation between light absorption and the structure of matter with the result that in recent decades a number of excellent discussions of the theory of electronic spectroscopy (UV-VIS and luminescence sp,~ctroscopy) have been published. Consequently, this extremely ivteresting aspect of molecular spec troscopy has dominated the teaching of the subject both in my own lectures and those of others. However, it is often overlooked that, in addition to the theory, applications of spectroscopic methods are of particular interest to scientists. For this reason, a lecture series about electronic spectroscopy given in the Institute for Physical Chemistry at the Heinrich-Heine-University in Dusseldorf was supplemented by one about "UV-VIS spectroscopy and its applications". This formed the basis of the present book.
