Yp. Sun et al., EFFECTS OF SOLVENT ENVIRONMENT ON VIBRONIC STRUCTURES OF THE C-70 FLUORESCENCE-SPECTRUM - REVERSE HAM BEHAVIOR IN SOLVENT POLARITY DEPENDENCE, Journal of the Chemical Society, Chemical Communications, (18), 1994, pp. 2099-2100
Strong solvent dependence of vibronic structures in C-70 fluorescence
spectrum, in the opposite direction from the Ham effect observed in be
nzene and pyrene, is attributed to perturbations in vibronic coupling
and/or polarity dependence of excited state potential energy surface.
