Temperature dependence of the solvated electron absorption spectra in propanediols

Using nanosecond pulse radiolysis, the absorption spectra of the solvated electron have been recorded at different temperatures from 295 to 498 K in 1,2-propanediol (12PD) and 1,3-propanediol (13PD). In both solvents, the optical spectra shift to the red with increasing temperature. While the shape of the spectra does not change in 13PD, a widening on the blue side of the absorption band is observed in 12PD by increasing the temperature from 296 to 473 K. (C) 2004 Elsevier B.V.
