The H2 and CH, chemical ionization mass spectra of the olefinic esters methyl acrylate, methyl methacrylate, methyl crotonate, methyl 3-butenoate, methyl 2-methyl-2-butenoate, methyl 3-methyl-2-butenoate and methyl cinnamate have been determined. In addition to the expected loss of CH,OH from [MH]+,

Chemical ionization mass spectra of exo-and endo-2-norbornanols and their phenylnrethane derivatives have been obtained with several reactant ions. Small differences are noted in the abundances of norbornyl and [M+H]' ions for the phenylnrethane derivatives: more norbornyl ions with the ex0 compound
Using specific deuterium labelling the mechanisms of the olefin elimination reactions leading to formation of [C,H,]+ in the H, and CH, chemical ionization mass spectra of ethylbenzene and n-propylhenzene (and to [C,H,C,HJ+ in the CH, chemical ionization mass spectra) have been investigated. The res
