Vibronic levels of the (1)A(2) State of SO2 were excited by crossing a supersonic jet of SO2 with laser radiation corresponding to cold bands in the 3045-3005 Angstrom region, and the emission spectrum was detected under different laser-jet geometrical alignments. When the exciting laser beam was allowed to cross the jet just outside the spectrometer’s field of view, a vibrational fluorescence spectrum of simultaneously excited low 1A, levels was measured and was found to be independent of the exciting wavelength. This indicated that these levels were populated through inelastic collisions within the jet and that the low-lying (1)A(2) levels do in general fluoresce back to the ground state. Fourteen band origins near the (1)A(2)(0,0,0)’ --> (1)A(2)(0,0,0)" transition at 3581 Angstrom were thus identified to within +/-1 Angstrom. An excitation spectrum recorded while monitoring the fluorescence of these collision-populated low (1)A(2) levels showed many cold bands that have not been detected before and also showed that the efficiency of energy transfer due to collisions depended on the initially excited vibronic level.
