The formation of [ M -2HI" ions has been reported in the field desorption mass spectrometry of saturated hydrocarbons. It is shown that these ions predominantly have an alkene structure and that a field-induced ion chemistry in multimolecular or condensed layers produce [M -2nHI + ' and [2M -2rnH]+'
Positive-ion fast atom bombardment (FAB) mass spectra of &vowl a d steroid glycodes with sodium chloride added showed well known characteristic features of the appearaoce of [M + Nal' peaks, disapperrance of ( M + HI+ perks and a significant decrease in the peak beights of fragment iom Compared with
