Picosecond laser-induced quantum beats have been observed in the fluor
escence emission from the 10V and 15V systems of jet-cooled CS2. Analy
sis of these quantum interference effects provides information on coup
ling between the B-1(2) V System and the A-3(2) R system. Complementar
y, rotationally resolved spectra of the 10V and 15V systems, which cor
roborate the information extracted from the time-resolved study have b
een obtained.
