NNS is produced by flash vacuum pyrolysis of 5-aryl-1,2,3,4-thiatriazoles 1, 3, 5, and 7 and 5-phenoxy-1,2,3,4-thiatriazole (9).The Ar matrix infrared spectrum shows νNN at 2039 cm-1 and νNS at 752 cm-1.The expe
Infrared spectra of new sulfur-nitrogen species in solid argon

New sulfur-nitrogen species were produced in an argon/nitrogen/sulfur vapor microwave discharge, and the reaction products were trapped in solid argon at 12 K. Nitrogen-15 and sulfur-34 isotopic substitutions, concentration variation, photolysis, and changes upon annealing provided a basis for identification and characterization of the new products. A product absorption at 1209.4 cm-1 is identified as the diatomic SN radical. The strongest product absorption at 1225.2 cm-1, which shows a triplet and a doublet pattern with mixed sulfur and mixed nitrogen isotopes, respectively, is assigned to the antisymmetric stretching vibration of the NS2 radical; these isotopic data provide a 153 ± 5° measure of the valence angle in NS2. The less stable NSS isomer absorbs at 1017.1 and 594.6 cm-1 and is converted to NS2 with near-ultraviolet photolysis. An absorption band at 2040.2 cm-1 shows quartet and doublet patterns with mixed nitrogen and sulfur isotopes, respectively, and is assigned to the nitrogen-nitrogen stretching fundamental of N2S. Evidence for higher nitrogen sulfides is also presented.
