Advances in Molecular Spectroscopy, Volume 3 provides information pertinent to the fundamental aspects of inorganic molecules and complexes. This book covers a variety of topics, including infrared spectrum, polyatomic ions, infrared emissions, and Raman spectra. Organized into five parts encompassing 72 chapters, this volume begins with an overview of the infrared spectrum of pyridine. This text then examines the results from studies of the infrared and Raman spectra of N2O4 in the solid and liquid phases at low temperatures. Other chapters consider the infrared spectrum of a mixture of N2O3 and N2O4, which has been studied in the liquid phase from 2 to 25 µ and in the solid phase from 2 to 35 µ, both at low temperatures. The final chapter describes the instrument developed for the measurement of rotatory dispersion and discusses some of the results obtained in the study of the complexes. This book is a valuable resource for chemists.
