The effect of the pressure on the solvation dynamics of coumarin 480 in ethanol has been studied by means of time-resolved emission using the time-correlated single-photon-counting technique with 20-ps resolution. The solvation dynamics slow with pressure. The pressure was varied from atmospheric pressure to about 1.8 GPa, the liquid-solid phase transition. At low pressures,
