The formation of ions of the cyclic depsipeptide valinomycin by field desorption has been investigated in detail. The ratio of molecular ions M+' to protonated molecules (M + HI+ has been found to be independent of emitter heating current and the nature of particular additives to the solution. In co
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]+'
