Brown and Carrington then show how the fundamental Dirac and Breit equations may be developed to provide comprehensive descriptions ofthe 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 Hamiltonian used to analyse and understand the experimental spectra of diatomic molecules. The remainder of the book concentrates on experimental methods.  \nThis book will be of interest to graduate students and researchers interested in the rotational spectroscopy of diatomic molecules.  \n􀀁􀀂􀀃􀀄􀀅􀀆􀀇􀀈􀀉 􀀃􀀊􀀋􀀉􀀁􀀌􀀋􀀂􀀅 􀀍􀀁􀀆􀀉􀀎􀀁􀀉 􀀍􀀉􀀅􀀆􀀉􀀍  \nSeries Editors:  \nRichard J.
