The equilibrium between a solvent cavity-localized electron, ecav –, and a dimeric solvent anion, (CH3CN)2 •–, which are the two lowest energy states of the solvated electron in acetonitrile, has been investigated by pulse radiolysis at 233–353 K. The enthalpy and entropy for the ecav – to (CH3CN)2...
