Résumé

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.
