Abstract

The chemical ionization mass spectrum of peroxyacetylnitrate, a major component of photochemical smog highly toxic to man and plants, was obtained using both methane and isobutane as reagent gas. The spectrum contains a [M + H]^+^ ion at m/e 122, intense fragment ions at m/e 43 [CH,CO]^+^ and m/e 46 [NO~2~]^+^, and less intense ions at m/e 61 [CH,ONO]^+^, m/e 77 [CH30NOz]^+^ and m/e 88 [^+^Oο£½CCH~2~ONO] formed by internal rearrangements. These results confirm the commonly accepted structure for peroxyacetylnitrate, CH~3~(CO)OONO~2~.

## Abstract The negative chemical ionization mass spectra of nitrobenzene, ethylene glycol dinitrate and nitroglycerine have been obtained using various reagent ions. For nitrobenzene, [OH]^βˆ’^ gives the [M βˆ’ H]^βˆ’^, together with [M]^βˆ’Λ™^ ions formed by electron capture, but other reagent ions gave r
