Abstract

Bipolar disorder: Femtosecond spectroscopy of samples in protic and aprotic solvents of similar polarities reveals that charge-transfer processes are substantially facilitated by the formation of solute-solvent hydrogen-bond networks (see picture). This notion of molecular-specific interactions is not part of the continuum dielectric models of solvation and should be of significance to biological processes such as those of enzymes.
