Ion kinetic energy spectrometry has been utilized to investigate the loss of CO from [p‐Z‐C 6 H 4 ‐CO] + and [C 6 H 5 CO] + ions generated from substituted acetophenones and benzo‐phenones. The variation of the leaving group in forming the [C 6 H 5 CO] + ion has no detectable effect on the kinetic energy release observed in the subsequent decomposition reaction. A substituent effect consistent with the assumption that substituted benzoyl ions have no memory of their origin is also observed.
