Abstract : The mass spectra of deuterated species shows that both the isomeric ions (CH2=SH)(+) and (CH3-S)(+) are formed in the ratio 2:1 from CH3SH; the ions (CH3CH=SH)(+) and (CH3CH2S)(+) in the ratio 0.8:1 from CH3CH2SH; and (CH2=OH)(+) and (CH3-O)(+) in the ratio 6.7:1 from methanol. The heats of formation of (CH3S)(+) and (C2H5S)(+) are of the order of 222 and 203 Kcal/mole respectively. The isomeric ions cannot be distinguished on thermodynamic grounds. (Author)
