Abstract
The well known temporary disappearance of the SO 2 spectrum following flash photolysis under adiabatic conditions has been shown to be an optical illusion induced by temperature broadening of the banded structure. A similar phenomenon has been observed for NO 2 following flash irradiation with wavelengths above 400 nm . The two spectra previously ascribed to a thermal isomer of SO 2 have otherwise been accounted for. The first, a continuous absorption below 240 nm , is the result of temperature broadening of the (C–X 1 A 1 ) system of SO 2 and the other, a series of bands in the 180 nm region, belongs to one of two new triplet systems of SO (D 3 II–X 3 ∑ – and E 3 II–X 3 ∑ – ). These two systems of SO fit a Rydberg series for an ionization potential of 9.8 eV.Keywords
