The kinetic shifts for an ion decomposition involving loss of CH 2 CO from a series of substituted acetanilide ions have been calculated using the Rice‐Ramsperger‐Kassel‐Marcus theory. The results indicate that in the main the observed changes in appearance potential‐ionisation potential for this reaction are due to a change in the number of degrees of freedom on introducing the substituent and not due to a substituent effect on the critical energy of reaction.
