The positive and negative ion mass spectra of some nitro- and polynitroacenaphthenes

Abstract

The positive and negative ion 70 eV mass spectra of thirteen nitro- and polynitro-acenaphthenes are reported. The postulated fragmentation paths, many of which are supported by metastable ion evidence, are interpreted in terms of structural features of the molecules and stabilities of the products formed. The significant similarities and differences between the two types of spectra are rationalised where possible.
