摘要：

A method is presented for predicting the shape of the metastable peak resulting from two metastable fragmentations taking place consecutively in the first field-free region of the GEC/AEI MS902S mass spectrometer. Distributions of released kinetic energy for the pair of reactions: m1+ → m2+ + x; m2+ + m3+ + y, derived from their respective metastable peaks, were used in a Monte Carlo simulation of the two-stage consecutive metastable fragmentation: m1+ {A figure is presented} (m2+) {A figure is presented} m3+. Results are presented for the reactions C2H5N+ →C2H4N+ + H-; C2H4N+ → C2H2N+ + H2; C2H5N+ → C2H2N+ + H2 + H∓. The method canreadily be extended to multistage decompositions. © 1979.
