Coumarin 102 (C102), was investigated in polar and hydroxylic solvents. Analysis of these
spectroscopic measurements using semiempirical solvent polarity scales (ET (30), Kamlet
and Taft) showed that the stabilization of the excited singlet state is mainly governed by
dipolar and hydrogen bonding interactions. This particuliar behavior was reflected by a good
adequacy between the present measured solvation times and the microscopic (or …
