Abstract

Abstract The loss of CH 2 from the molecular ion of phenoxyacetic acid and the expulsion of an Hatom from ionized anisole lead to phenoxymethylen ions, which fragment predominantly by CO loss on the microsecond time-scale. Carbon-13 labelling reveals that∼ 90% of the CO molecules expelled from the metastable ions derived from phenoxyacetic acid incorporate the carbon atom from the 1-position of the phenyl group of ...
