✦ Synopsis

Product studies using FTIR absorption spectrometry have been performed in a 420 P reaction chamber on the 254 nm photolysis of mixtures containing CH3SSCH3 and NO* at ppm concent~tions in 760 Torr of OzMz diluent. The results indicate that the C&S radicals formed by photolysis of CH,SSCH, react primarily with NO*, forming CH$O and NO. In the presence of O2 an unstable intermediate whose IR absorption spectrum resembles a peroxynitrate compound is observed. The intermediate has been tentatively assigned to methyl suIfiny1 peroxynitrate, CHIS(0)OONOZ. Other products indude SOI, CH$NO, CHsSNOz, CI-&N09, CH3SOjH, and HCHO.
