Negative-ion chemical ionization (NCI) and collisionally activated mass spectra are presented for heptafluorobutyryl (HFB) esters of eight trichothecenes. The ion-source conditions have a dramatic effect on the NC1 spectra and only at low source temperatures can intense parent ions, i.e., M -for bis
