Abstract : Preliminary femtosecond spectroscopic studies of primary events occurring in the neat dimethylsulfide at 294 K following initial energy deposition are presented. A transient induced absorbance in the infrared 1330 nm appears in 120 fs after the ultraviolet photoionization of dimethylsulfide. Considering scavenging experiments, we assign this signal to the solvated electron MATH. In the visible spectral region MATH = 420 nm, a short lived species, formed in less than 300 fs has been observed. A tentative assignment of this transient component is directed toward the existence of a solvated or complexed form of the primary anion resulting from the direct electron attachment to solvent molecule.
