unit is cm-1.
WELLER CORRELATION
Empirical correlation for the energy of full charge-transfer exciplexes
relative to the ground-state in n-hexane as a function of the electrochemical
one electron oxidation and reduc-tion potentials measured in a polar solvent
for the donor (D) and the acceptor (A) involved (see e.g.: A. Weller, in "The
Exciplex", Gordon and Ware eds., Academic Press Inc., N. Y., 1975):
