✦ Synopsis

The mechanism of H$O4 formation via the reaction steps, SO1 t O$SO "*' 3-(SO,: H,O) +H,SO,, has been investigated at low temperature in an argon matrix. Photooxydation of SO2 mainly occurs through the SO*: O3 pairs. Photolysis of a SOI-H20-0, mixture did not lead to the H,SO, molecule. The I : 1 HZO: SO9 complex was identified in nitrogen matrix. Observed isotope shifts in the IR absorption of the water submolecule suggest that the complexation proceeds through charge transfer with an O...S interaction.
