Electron spin echo modulation studies of O/sub 2//sup -/ in specifically deuterated methanol and ethanol glasses have been carried out at 4.2/sup 0/K to determine the solvation structure around O/sub 2//sup -/. The results of the analysis indicate that in both the cases each O/sub 2//sup -/ is solvated by four alcohol molecules. In the case of methanol, the solvent molecules have their H-O bonds oriented toward the II* orbitals of O/sub 2//sup -/ to maximize hydrogen-bonding interactions. This is similar to the O/sub 2//sup -/ solvation structure in water. However, in ethanol the H-O bonds are tilted away from the II* orbitals so that partial molecular dipole orientation of ethanol occurs. As the polar solvent molecule becomes bulkier it appears that molecular dipole orientation becoms more important. This tend is compared with results for solvated electrons in the same solvents. 9 figures, 1 table.
