“…However, recently AIyers (13,14) has reinvestigated the compound and has shown conclusively bq means of stoichioinetry, molecular weight determination, mass spectrometry, and n~icrowave spectroscopy that -the correct formula is in fact S 2 0 , the thioanalogue of SO2. Thus the compound prepared by Schenk, the intermediate observed bl Ei~lanuel a t room temperature, and the end product observed in the flash-photolj7sis of HZS/02 mixtures a t rooin temperature by Norrish and Zeelenberg (15,16) must all be considered as SzO, disulphur monoxide.…”

The oxidation of hydrogen sulphide has been followed mass-spectrometrically by direct sampling from a reaction vessel having a small leak. In the neighborhood of the third explosion limit, there is a period of 8-12 seconds of accelerating reaction before the explosion; during this time peaks are observed to grow, disappearing after explosion. By using D2S/lB02 and HzS/1802 mixtures, it has been shown that these peaks arise from the ions HZ+, S20+, H2SO+, Szf, and H2Szf. I t is evident that the first two ions represent the intermediate formation of hydrogen and disulphur monoxide; the parents of the last three ions are discussed, and it is concluded that the most likely possibilities are HzS02, Ss, and H2Sz. Only during the explosion itself is there any evidence for SO radical.
