A collision-induced dissociation (CID) study of five synthesized nitramines was carried out using a hybrid EBQQ mass spectrometer. CID spectra were obtained in two modes: B/E linked-scan mode and MS/MS mode using the EB sector combination as the first mass spectrometer and the QQ as collision cell and second mass spectrometer, respectively. Fragmentation pathways of the compounds were determined in the electron-impact mode. It was found that dominant fragmentation pathways included the loss of OH, NO2 and HNO2 in addition to the loss of CH2NNO and CH2NNO2. (Copyright (c) 1990 by John Wiley and Sons, Ltd.)
