Empirical correlations between solvent acidity and the optical characteristics of solvated electrons

Photochemically Triggered Alkylthiol Reactions on Highly Ordered Pyrolytic Graphite

“…Acetonitrile and ethanol are known to be better solvents than DMF for stabilizing both solvated electrons and anion species. , The stabilization of solvated electrons correlates positively with the λ max of bound–bound optical transitions, − which for solvated electrons in DMF, acetonitrile, and ethanol are reported at 1680 nm, 1450 nm , and 680 nm, respectively. The shorter the λ max , the greater the stabilization and, consequently, the lower the expected threshold energy needed to generate solvated electrons at the HOPG/liquid interface.…”
