Rotational Spectroscopy of Diatomic Molecules

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.
