The dynamic solvent effect on the intramolecular charge-transfer (ICT) -state formation of 4- (9-anthrylmethyl) -N, Ndimethylaniline (AMDMA) in the excited state was examined by using picosecond time-resolved fluorescence spectroscopy at high pressures. The non-exponential population decay of the local excited (LE) -state emission is analyzed by fitting to a double exponential function. As solvent viscosity increases, the rate of the ICT-state formation becomes noticeably faster than the solvent relaxation time, which is gauged by the longest component of longitudinal relaxation time of the solvent (τ<SUB>L</SUB>). The pressure effect on the ICT reaction of AMDMA in the excited state can be accounted for in terms of the "pressure tuning effect of the solvent viscosity".
