Excited-State Proton-Transfer Kinetics: A Theoretical Model

Article abstract of DOI:10.1021/j100314a022

The intersecting-state model is applied to excited state proton-transfer reactions.The results are consistent with those previously obtained for the analogous ground-state reactions.The transition-state bond order n^* is similar in the ground and excited states: carbon acids have lower n^* than nitrogen or oxygen acids.The mixing entropy parameter λ is found to be lower for excited-state than ground-state reactions.The mechanistic implications of this are discussed.
