    Notes: Mass spectra of a series of alkyl, alkyl/aryl and biologically important quaternary ammonium and phosphonium compounds have been obtained by a direct thermal process. No means of ionization other than the heating of a salt coated filament is used. The spectra consist primarily of even electron ions for which decomposition schemes involving four-center reactions are proposed. These spectra are similar to those obtained in fission fragment induced desorption, laser induced desorption and field desorption/collisional activation, but they are produced by a far simpler means.
