✦ Synopsis

The nature of weak electron-phonon couphng in molecular crystals is discusxd briefly. Evpcrimcntal WLhniqucs ;ltc suggested for diffcrcntiating between linear. quadratic and vibronic Hcrzbcrg-Teller or non-Born-Oppcnhcimcr coupling mcchani\ms. The coupling of phononc to the benzene S,-, .= S1 transitlon is examined in light of recently rcportcd expcrimental results It Is found that non-Horn-Oppenheimer vibromc couplmg plays an important role in determining the intcnsity and structure of th obscrvcd phonon sidebmds.

Radiative lifetimes of the lowest triplet states are determined for several aromatic hydrocarbons from the measured fluorescence quantum yield, phosphorescence quantum yield, and lifetime of phosphorescence. It is found that the radiative lifetime is considerably Iorger for pcrdeuterated naphthalen

Rotational perturbations are identified in Doppler-free two-photon spectra of the 14' 9 and 14r 0 1' 9 vibronic bands in ChH6. Evidence is found that Coriolis coupling between some of the rotational levels of two distinct vibrational states within St is the mechanism responsible. Thin coupling mecha
