Abstrakt:	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−1 respectively. The isomeric ions cannot be distinguished on thermodynamic grounds. [ABSTRACT FROM AUTHOR]
