摘要：

Deuterium isotope effects on the solvation dynamics of methanol have been investigated using the femtosecond fluorescence up-conversion technique. Deuterated methanols (CH3OD, CD3OH, and CD3OD) show slower solvation dynamics than normal methanol. The isotope effect arising from the OH group is about 10% and that arising from the CH3 group is about 5%, which are explained by the effects of hydrogen bonding and the frictional constant, respectively.
