activation energies of various hydridetransferreactions was developed according to transition state theory using the Morse-type free energy curves of hydride donors to release a hydride anion and hydrideacceptors to capture a hydride anion and by which the activation energies of 187 typical hydride self-exchange reactions and more than thirty thousand hydride cross transferreactions in acetonitrile were

It has been shown that the rate of symmetrical hydridetransfer reaction varies with the hydride affinity of the (identical) donor and acceptor. In that case, Marcus theory of atom and group transfer predicts that the Bronsted α depends on the location of the substituent, whether it is in the donor or the acceptor, and the tightness of the critical configuration, as well as the resemblance of the critical

parameters that control the reaction barriers, the kinetics of excited-state OH– release from a series of acridinol photobases were studied using transient absorption spectroscopy. The rate constants were obtained in three solvents (methanol, butanol, and isobutanol), and the data were modeled using Marcustheory. The intrinsic reorganization energies obtained from these fits were found to correlate
