Notes:
Mass-analysed ion kinetic energy (MIKE) spectrometry with collision-induced dissociation (CID) has been used to study the fragmentation processes of the MH+ ions produced by chemical ionization (CI) of a series of deuterated hexanitrostilbene (HNS) and hexanitrobibenzyl (HNBB) compounds. Typical fragment ions obtained in both groups were due to loss of OR′, 2OR′ and NO2 and due to the cleavage of the CC single bond in HNBB and of the double bond in HNS. In HNS there is a preferential loss of NO. A great similarity was observed between the fragmentation pattern of 2,4,6-trinitrotoluene (TNT) and that of HNS. In negative-ion chemical ionization (NCI) the fragment ion which forms the base peak in the mass spectra of the HNS compounds is the [(M/2)+O]- ion, while in the HNBB compounds it is the [M/2]- ion.
