We present a theoretical calculation of predissociation lifetimes for the vibrational levels of the H2 molecule in the 2 311a state. Our results predict that vibrational lifetimes decrease with t, up to u= 8 and then remain practically constant. Agreement with available experimental data is good. Fi

✦ Synopsis
With time-resolved spectroscopy of the fluorescence transitions 2 3Hg(,Q)-~ 1 3£u radiative lifetimes z(.Q), quenching cross sections cr(S'2) and the population mechanisms of the 2 3Fig(g2= 0, 1, 2 ) states under optical excitation of levels in the 3 ~Eu state have been determined. The results for the different g2 components are: rrad(12) = 20--22 ns, cr(£2) = 685-880 A2.

The laser-and collision-induced fluorescence of Li2 molecules in a heat-pipe, excited by a tunable frequency-doubled mode-locked cavity-dumped cw dye laser into selected rovibrational levels of the C lI1. state, was observed with spectral resolution using a monochromator and with temporal resolution
The 193 nm photolysis of acetylene has been used as a source of &(B 'Z: ) radicals, which are subsequently detected by laserinduced fluorescence technique. The pressure-dependent collisional lifetimes of this radical are experimentally determined by delaying the probe laser with respect to the photo
Model potential calculations of the B r Du-X r xz transition dipole moment are used in conjunction with the empirica potential energy curves of Vidal and Hessel to calc&te the radiative lifetimes of the vibrational levels of the B r Du state.

The fragment HCO, produced from acetaldehyde by photolysis at 300 nm, was detected by laser-induced fluorescence of B 'A'g 'A' transitions. The fluorescence lifetimes of the HCO B state decrease rapidly as the photolysis energy increases, indicating strong predissociation of the B state. The radiati
