The positive electron impact (EI) and isobutane chemical ionization (CI) mass spectra of six nitramine nitrates were studied with the aid of some accurate mass measurements. In the EI spectra, fl fission relative to both the nitramine and nitrate ester is important. In the C1 spectra a major ion occ
Electron impact mass spectra at 70 eV electron energy and chemical ionization mass spectra with ammonia as the reagent gas are reported for certain unsaturated C-glycosides. Comparisons are made between the mass spectra of anomeric pairs of these glycosides. ## 246 ( 5.8). 228 (1.2), 181 (1.5), 15
