Excited States, Volume 4 is a collection of papers that deals with the excited states of molecular activity. One paper investigates the resonance Raman spectroscopy as the key to vibrational-electronic coupling. This paper reviews the basic theory of Raman scattering; it also explains the derivation of the Raman spectra, excitation profiles, and depolarization ratios for simple resonance systems. Another paper reviews the magnetic properties of triplet states, including the zero-field resonance techniques, the high-field experiments, and the spin Hamiltonian. This paper focuses on the magnetic properties of triplet states through magnetic resonance experiments applied in the presence or absence of such fields. Another paper analyzes the effects of a magnetic field on molecular luminescence. This paper also describes the investigations made to the quenching of molecular luminescence in the presence of a magnetic field from molecules such as glyoxal, as well as some applications of magnetic quenching. One paper reviews the time-dependent behavior of excited molecules. This paper explains the essential features of "intermediate" cases encountered in the photo-physical time-dependent studies of excitable molecules by comparing theoretical aspects and experimental data. Nuclear scientists, physicists, and researchers whose works involve molecular chemistry and solid state physics will find this collection valuable.
