Abstract

The basic experimental and theoretical concepts underlying molecular spectroscopy are presented. The equations and relations needed in practical applications of high-resolution spectroscopy are provided. Group theoretical tools and their use in high-resolution spectroscopy are introduced and illustrated by simple examples. Time-dependent processes and quantum dynamics are presented and discussed in relation to spectroscopic observations. Coherent and incoherent radiative excitation and radiationless transitions are treated in relation to applications in molecular spectroscopy.
