he doubly charged [MI\*+, [M+1I2+ and [M-O]'+ ions are observed in the field ionhtion mass spectra of para substituted acetophenones. "he effect of the type of the substituent on the formation of the doubly charged ions is described.

β¦ Synopsis
Abstract
The observation of doubly charged ions in field ionization with blade or wire emitters does not in itself indicate that high excitation energies (β₯ 17 eV) are accessible through gas phase ionization with such emitters.

Alkenic compounds when subjected to chemical ionization with NO+ yield two acylium ions by oxidative cleavage of the double bond. Studies on the mechanism of formation of these ions are reported.
