Pulse radiolysis study of solvated electrons in water--ethanol glasses at 76K. Structure of the first solvation shell around the electron
The initial spectrum of the trapped electron at less than or equal to 200 nsec in anhydrous C$sub 2$$D$$sub 5$OD glasses at 76$sup 0$K has lambda/sub max/ approximately 1300 nm and shifts with time to a stable position near 540 nm. The presence of water in C$sub 2$$D$$sub 5$OD--D$sub 2$O glass causes a large increase in the visible portion and a decrease in the infrared portion of the initial spectrum, suggesting that the initial time scale for the solvation process is more rapid when a water molecule is in the first solvation shell of the electron, or that water induces specific structural arrangements of shallow trapping molecular configurations. From the effect of water on the spectra, a simple analysis indicates that there are four molecules in the average first solvation shell of the electron. (auth)
