| Abstract
| - Photodetachment cross sections for a series of cyclic enolates were measured using a continuous wave (CW)ion cyclotron resonance instrument to generate and detect the ions. We report electron affinities for the radicalscorresponding to the removal of the extra electron from the following anions: 2-methylcyclopent-1-enolate,3-methylcyclopent-1-enolate, 4-methylcyclopent-1-enolate, 5-methylcyclopent-1-enolate, 2-methylcyclohex-1-enolate, 3-methylcyclohex-1-enolate, 4-methylcyclohex-1-enolate, 4-ethylcyclohex-1-enolate, 5-methylcyclohex-1-enolate, and 6-methylcyclohex-1-enolate. Some of these anions are mixed with their tautomers,derived from deprotonation of the parent ketone; the consequences of this are analyzed. The effect of alkylationon the electron affinities is discussed. The effect of vibrational modes on the lifetimes of the dipole-boundstates of 4-methylcyclohex-1-enolate and 4-ethylcyclohex-1-enolate is discussed.
