The temperature dependent absorption spectra of solvated electrons in some simple alcohols and four poly-alcohols, 1,2-ethanediol, 1,2-propanediol, 1,3-propanediol, and glycerol, have been systematically investigated by nanosecond pulse radiolysis techniques. The effects of molecular structure, especially the chain length and the number of OH group, on the absorption peak position are demonstrated. On the other hand, the temporal behaviours of solvated electron in methanol and the four poly-ols are studied by scavenging method and direct measurement using picosecond pulse radiolysis.
