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
