Molecular Quantum Mechanics and Molecular Spectra, Molecular Symmetry, and Interaction of Matter with Radiation

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