Abstract The expulsion of neutral fragments of masses 27 and 28 from metastable [M OH] + ions derived from 2‐nitrotoluene has been observed. The relative abundances of the resulting fragment ions, together with the kinetic energy released in each process, has been compared with similar fragmentation of [C 7 H 6 NO] + ions derived from other precursor molecules. In this way, the nature of the neutral fragments and the structure of the [M OH] + ions from 2‐nitrotoluene has been investigated. The most likely structure is the 1,2‐benzisoxazolenium cation although the coexistence of other structures cannot be ruled out on the present evidence.
