Popis:	Hydroxide ion chemical ionization mass spectra of two classes of trichothecenes are described. The spectra provide molecular weight information as well as fragment ions indicative of structure. The discussion of fragmentation is aided by the use of high resolution mass measurements, mass analyzed ion kinetic energy spectra and chloride attachment spectra. Certain novel fragmentation processes under hydroxide ion conditions are noted. The chloride attachment spectra are also useful for verification of molecular weight.
