The photochemistry of the I- ion in D2O, ethanol, methanol, isopropyl alcohol, and methyl cyanide is investigated and the results compared to those previously obtained in H2O solutions. It is shown that solvated electrons appear as a detectable intermediate in all these solvents and that the cross section for primary dissociation, Γ, is solvent dependent. The kinetic behavior in the case of D2O is analogous to that previously proposed for H2O solutions. The rate constant of the cage scavenging reaction H + H+ in H2O is found to be equal to that of D + D+ in D2O.
