investigated at low temperature in an argon matrix. Formation of stable SO3 occurs from the reaction between SO2 and O(1D) and also by oxygen atom transfer within the SO2:O3 complex. Use of isotopic SO2 species led to unusual observations suggesting that photooxidation of SO2 proceeds via an intermediate species, namely, OSOO; this trioxide sulfur isomer transforms into SO3 by tunneling.
