The current volume in the series, Vibrational Spectra and Structure, is a single topic volume on gas phase structural parameters. The title of the volume, Equilibrium Structural Parameters, covers the two most common techniques for obtaining gas phase structural parameters: microwave spectroscopy and the electron diffraction technique. Since the quantum chemical method provides equilibrium geometries, the volume is an attempt to provide a connection between the experimental and theoretical parameters.The book provides a review on molecular structure determinations from spectroscopic data using scaled moments of inertia. The limited number of molecules for which equilibrium parameters have been obtained and the requirement of a large number of microwave data needed to obtain the equilibrium structural parameters is noted. Electron diffraction technique is reviewed, along with a description of how this can incorporate structural information from microwave spectroscopy, vibrational spectroscopy, or theoretical calculations to improve the determination of the structural parameters by electron diffraction studies. Also discussed are the theory and methods of microwave spectroscopy, describing in some detail ro and rs structures as well as rm structures and corrections based on ab initio calculations. The accuracy of the molecular geometry predictions by quantum chemical methods is considered in some detail with data presented in graphic rather than tabular form. This makes it possible to readily note the difference in the parameters predicted at the various levels of quantum mechanical calculations. The four authors have provided a coherent description of the various structural parameters obtained experimentally along with treatments needed to extract equilibrium bond distances and angles.

TRAC: Trends in Analytical Chemistry, Volume 7 provides information pertinent to the trends in the field of analytical chemistry. This book discusses a variety of topics related to analytical chemistry, including biomolecular mass spectroscopy, affinity chromatography, electrochemical detection, nucleosides, and protein sequencing. Organized into 63 parts encompassing 158 chapters, this volume begins with an overview of the significance of quality and productivity in the analytical laboratory. This text then presents a comprehensive review on alcohol dehydrogenases, immobilization, and applications in analysis and synthesis. Other chapters consider the various tests for determining the excellence of quantitative assays available for analysts to utilize for method validation. This book discusses as well the primary challenge of neuropharmacologists to relate physiological functions to the many ligand binding sites identified in brain tissue. The final chapter deals with the fundamentals and applications of biosensors. This book is a valuable resource for analytical chemists, chemical engineers, clinical chemists, neuropharmacologists, and scientists.
