内容説明
Written to be the definitive text on the rotational spectroscopy of diatomic molecules， this book develops the theory behind the energy levels of diatomic molecules and then summarises the many experimental methods used to study their spectra in the gaseous state. After a general introduction， the methods used to separate nuclear and electronic motions are described. Brown and Carrington then show how the fundamental Dirac and Breit equations may be developed to provide comprehensive descriptions of the kinetic and potential energy terms which govern the behaviour of the electrons. One chapter is devoted solely to angular momentum theory and another describes the development of the so-called effective Hamiltonians used to analyse and understand the experimental spectra of diatomic molecules. The remainder of the book concentrates on experimental methods. This book will be of interest to graduate students and researchers interested in the rotational spectroscopy of diatomic molecules.
Book Description
Diatomic molecules are important to the physical sciences because they are the basic building blocks of large molecules. Many of the principles which underly our understanding of chemical bonds in molecules were first developed by studying diatomic systems. Starting from fundamental principles， this book develops a theory that analyzes the energy levels of diatomic molecules and summarizes the many experimental methods used to study the spectra of these molecules in the gaseous state.
