“…-]. The above peaks are consistent between the two sources as well as those observed with NCI literature spectra using filament thermionic emitters [35,37,39]. Finally, the small peak at m/z 176 could be attributed to [(RDX -…”

“…3b) [28] and on basis of present 2D map (Fig. 3c), we assigned the first RI peak with K 0 =2.51 cm 2 The assignment of m/z 35 and 37 Da is straightforward ascribed to 35 Cl − and 37 Cl − formed via dissociative electron attachment to CCl 4 in CD. The presence of 35 Cl − and 37 Cl − in mass spectrum is easy to be recognised by the typical isotopic ratio 3:1 of these isotopes and this ration is typical also for all ions exhibiting Cl − .…”

“…This fragment has been postulated as triazine (C 3 H 7 N 3 ). Yinon and Hass [35])) studied structure of ions by collision induced dissociation (CID) of RDX ions ionized by chemical ionisation (CI) and triazine has appeared as one among other products of RDX. We assume that formation of this product in our experimental conditions is possible as well and (C 3 H 7 N 3 ) − is formed in ion-molecule reactions of RI to RDX.…”

“…As discussed by Yinon and Zitron, 12 the relative abundances of high-mass ions in electron-impact RDX spectra vary somewhat from instrument-to-instrument, apparently as a result of different ion-source and probe temperatures, as well as ion-source pressures. In high-resolution work discussed by Yinon, 13 75, 120, 128, and 148 were the major high-mass ions. Sometimes the molecular ion was not reported, and sometimes it is seen at very low levels (<0.1%).…”

“…However, after further consideration, we now judge that the variations shown in Table 1 (occurring at less than 150TC) probably result from changing pressure in the ion source and therefore from changing importance of ion fragmentation via adduct ions formed in the mass spectrometer ion source. For instance, Yinon has shown 13 that nme 128 results not from fragmentation of the RDX M-+ species but from [M+NO21+. Thus, the relative intensity of ion 128 would be expected to rise as the RDX vapor pressure rises, even if there is no thermal decomposition.…”
