Résumé

The elucidation of detailed mechanisms of ultrafast events that occur in molecular charge transfer or reaction dynamics has been made possible by recent advances in spectroscopy techniques that use ultrashort laser pulse generation. Ultrashort laser pulses (100 femtoseconds duration, 1 fs = 10-15 s) allow to initiate selective photochemical processes (single charge transfer for instance) and to obtain unique informations on the dynamics of primary steps of radical reactions involving ultrafast electron or proton transfer : formation of the hydration cage around an electron, encounter pair formation, ion-molecule reaction. Recent investigations on the non-equilibrium states of electron in aqueous media are discussed.
