Picosecond transient absorption measurements and simulations of the hydrated electron geminate recombination dynamics are presented for 4 eV multiphoton ionization of liquid H{sub 2}O and D{sub 2}O. To within the accuracy of the data and simulation, the isotope effect can be accounted for in terms of the decrease in the diffusion coefficients for e{sub aq}{sup -}, D{sub 3}O{sup +}, and OD. and the e{sub aq}{sup -} + D{sub 3}O{sup +} {yields} D reaction rate in D{sub 2}O. 14 refs., 1 fig., 1 tab.
