Pulse radiolysis study on the solvated electron in poly-ols

Lin, M.; Katsumura, Yosuke; Muroya, Yusa*; Fu, H.*; Yamashita, Shinichi; Mostafavi, M.*; Lampre, I.*

The molar extinction coefficients at the absorption maximum of the solvated electron spectrum have been re-evaluated to be 9 000, 9 700, 10 000 and 10 600 M$$^{-1}$$cm$$^{-1}$$ for 1,2-ethanediol (12ED), 1,2-propanediol (12PD), and 1,3-propanediol (13PD) and glycerol (GLY), respectively. These values are two-thirds or three-fourths of the value usually reported in the published report. With these extinction coefficients, the time-dependent radiolytic yields of the solvated electron in these diols from the ps to the $$mu$$s time range are described. The radiolytic yield in these viscous solvents is found to be strongly different from that of the aqueous solution. The temperature dependent absorption spectra of the solvated electron in 12ED, 12PD, 13PD, and GLY have also been investigated. In all these solvents, the optical spectra shift to the red with increasing temperature. The results, together with those of fs photochemistry studies carried out in Prof. Mostafavi's group, suggest that the solvation dynamics of electrons in these poly-ols is strongly related to the structure, especially the concentration of OH group.
