Solvated electrons at elevated temperatures in different alcohols; Temperature and molecular structure effects

Yan, Y.*; Lin, M.; Katsumura, Yosuke*; Fu, H.*; Muroya, Yusa*

The absorption spectra of solvated electrons in various alcohols were measured at different temperatures using pulse radiolysis technique, and then compared with currently available experimental data on the temperature dependent energy of absorption maximum of solvated electrons in monohydric alcohols, diols and triol. is larger in those alcohols having more OH groups at all the temperatures. The molecular structure effect, including OH numbers, OH position and carbon chain length, are investigated. For the primary alcohols with same OH group number and position, the temperature coefficient increases with increasing chain length. For the alcohols with same chain length and OH numbers, the temperature coefficient is larger for the symmetric alcohols than the asymmetric ones.
