The second moment of the ESR line shape of trapped electrons produced by codeposition of sodium and water vapor at 77/sup 0/K has been measured in H/sub 2/O and D/sub 2/O at both 9 and 35 GHz microwave frequencies. The sodium concentration is less than 0.01 M in this matrix. By analyzing the difference in the second moments in the protiated matrix at 9 and 35 GHz the isotropic and anisotropic hyperfine constants for n nearest equivalent interacting protons are obtained. The structural results found are similar to those obtained previously for trapped electrons in 10 M NaOH glassy ice by analysis of second moment and electron spin echo data. Since the trapped electron solvation structure seems independent of the solute concentration, we suggest that this solvation structure is also characteristic of solvated electrons in liquid water.
