| Abstract: | The optical absorption spectrum obtained by pulse radiolysis of pure liquid dimethylsulphoxide includes a broad intense band in the near IR with λmax  1500 nm. This band is assigned to solvated electrons with a half-life of 15 ± 2 nsec. The λmax of the solvated electron correlates better with dimethylsulphoxide's inability to solvate negative ions than with its dielectric constant, which is 48. |
