摘要：
An investigation of the negative-ion chemistry of 13 coumarin and three psoralen compounds is reported. Negative-ion chemical ionization was effected using O-. and OH- as the reagent ions; it was found that O-. leads preferably to [M - H + O]- whereas OH- mainly furnishes [M - H]-. The results of metastable anion fragmentation and collision-induced dissociation of mass-selected anions are presented.
