✦ Synopsis

Both alkenes and cydoallrenes react with [CH&H21". The possibilities and Limitations of CI(CHm2) for the identification of structural isomers and for the determination of double bond positions are discussed. The quasi-molecular ions + CH&Hz]" are shown to fragment in a manner observed for amines under MIKE conditiom rather than at 70 eV electron impact, which suggests that one is dealing with long-lived low-energy Species.

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
