Abstract

An attempt to investigate the vibrational bands near the origin of the E band of SO₂ has been made in a supersonic jet experiment. Several cold vibrational bands have been identified within the 32850-32880 cm^-1 region and their fluorescence spectra have been selectively excited and measured. A hot band activity at ≈ 32872 cm^-1 was found to persist at low rotational temperatures, which caused the Frank-Condon intensity pattern of the E band's fluorescence spectrum to vary when measured under slightly different cooling conditions. The band's upper levels were not all found to have the same vibronic symmetry as that of the E band.
