Metastable transitions in mass spectra of fifty-six hydrocarbons

Abstract

In the mass spectra of 56 saturated and unsaturated hydrocarbons, all the observable metastable tra ns itions have been identified. In 362 cases, t here are 32 different transitions involving loss of masses 2. 15, 16, 26, 27, 28, 29, 30, 42. and 44. The occurrence of a metastable transition depends on the in tensity of both the initial ion peak and th e final ion peak.
