内容説明
This book aims to summarize recently developed methods for the spectroscopic analysis of chemical equilibrium. The methods are applicable to virtually any spectroscopic technique that produces an output signal linearly dependent upon the concentrations of certain solution components. This criterion is met by UV/VIS, IR, fluorescence, CD, ORD, NMR, and ESR. Methods of evaluation applicable to each of these types of spectroscopy are dealt with explicitly in the text. The book itself is divided into three parts, each of which may be read independently. Part 1 provides the relevant theoretical and methodological background, as well as definitions for key technical terms. Part 2 is a systematic examination of an assortment of titration systems, including equilibria of the acid-base, metal complex, association (or bonding), and redox types. The treatment is limited to homogeneous phases; problems posed by precipitation or other phase separations are deliberately ignored.
The central theme of each chapter is a search for answers to two questions, firstly, what types of information can one derive solely on the basis of spectometric measurements, and secondly, how can this information be correlated with electrometric (pH) data in order to establish equilibrium constants? Part 3 is devoted to experimental considerations related to UV/VIS, fluorescence, CD/ORD, IR, Raman, and NMR, as well as the applications of these tools to the spectometric titration. At least one concrete example is provided with respect to each of the corresponding spectroscopic methods. The book concludes with an appendix listing two computer programs, EDIA and TIFIT, which the authors have found useful in interpreting their data. This book should be of interest to institutions and researchers in the fields of analytical, physical and inorganic chemistry.
