A spectroscopic study of Cl2 by VUV laser-induced fluorescence is reported for the first time. The free jet excitation spectrum in the region between 79000 and 80100 cm-1 revealed the contribution of some additional band systems other than the dominant 2 1Σu +←X 1Σg + transition system. The VUV and UV fluorescence lifetimes ranging from 15 ns down to 1 ns or less depended strongly upon the excitation wavelengths, but very little on the fluorescence wavelengths. Possible assignments of the excitation bands are discussed.
