Photooxidation of Sulfur Dioxide in Low-Temperature Matrices
Sodeau, John R.,Lee, Edward K. C.
, p. 3358 - 3362 (1980)
The mechanism of photooxidation of sulfur dioxide has been investigated at low temperatures.Monomeric sulfur dioxide was found to be photochemically inactive, and no evidence was found for existence of * in an oxygen matrix.In contrast, th
