Abstract
Experimental and theoretical resonance emission spectra are obtained for a number of vibrational states of SO2(C̃ 1B2). The experimental emission spectra are dominated by (n1ν1, n2ν2, 0) bands, but some weak activity in the anti-symmetric stretch (ν3) is observed. The calculated emission spectra based on an empirical near-equilibrium potential energy surface agree reasonably well with experiment for two lowest states investigated here, but fail to reproduce higher ones. Resonance Raman spectra are also calculated and agree well with an earlier experiment.
