This book teaches the analyst why it is advantageous to obtain vibrational data under different physical phases. Molecular vibrations are affected by change in physical phase, and knowledge of how certain molecular vibrations are affected by change in the chemical environment improves the analyst''s ability to solve complex chemical problems.This book is invaluable for students and scientists engaged in analytical and organic chemistry, since application of IR and Raman spectroscopy is essential in identifying and verifying molecular structure.This reference provides analysts with information that enables them to acquire the maximum amount of information when sampling molecular vibrations via IR and Raman spectroscopy.Key Features* Explains why it is advantageous to obtain vibrational data under different physical phases * Compiles many vibrational studies into a single compendium * Lists group frequencies in different physical phases * Reveals that some group frequencies are more affected than others by changes in the physical phase * Demonstrates that in-phase and out-of-phase vibrations of the same functional group are not equally affected * Describes how solute-solvent complexes differ with changes in the solvent system* Shows that the amount of Fermi resonance between a fundamental vibration and a combination or overtone is altered with change of physical phase * Written by an internationally recognized expert

Infrared Spectra of Inorganic Compounds is a comprehensive compendium of reference infrared spectra and empirical spectra-structure correlations of inorganic compounds in the solid phase. The majority of these compounds are (powdered) crystalline solids in which the crystallographic unit cell may contain several polyatomic ions or molecules. This book begins with an overview of the use of infrared spectroscopy in the identification of inorganic compounds. The experimental procedures for scanning the mid-infrared spectra are then described. The spectra are arranged to bring together compounds containing similar anions, in order to facilitate recognition of characteristic group frequencies. The arrangement is based on the position in the periodic table of the central atom in the anion. Two indices are provided, the first containing compounds as they appear in the book in numerical sequence, and the second arranged alphabetically by anion. Characteristic infrared frequencies and band intensities of the different anions are summarized, along with frequency assignments for the fundamental vibrations of complex anions taken from the literature. This monograph should be useful to physicists and inorganic chemists.
