Franck-Condon factor, hydrogen bonds, bond

Useful information can be obtained from the experimental determination of the activation energy and preexponential factor separately, since they are determined by different factors. According to the quantum mechanical theory, the value of the preexponential factor in proton transfer reactions is determined mainly by the characteristics of the chemical bond to be broken, whereas the activation energy is determined by the Franck-Condon potential barrier associated with solvent polarization. Experimental investigation of the hydrogen evolution reaction from the ions and CHaCNH" in water and in...
