AbstractThe ultrafast dynamics of chlorobenzene clusters upon excitation at 271nm have been studied by femtosecond pump-probe spectroscopy combined with time-of-flight mass spectrometric detection. From which the hot molecule mechanism is suggested. An ultrafast (~170fs) decay of the initially excited S1 state is tentatively attributed to the internal conversion to the high vibrational levels of S0 state. The shortening of the lifetime is discussed as a possible influence of the solvation effects. In addition, the secondary decay time (>1ns) reflects the dissociation process of the high vibrational levels of S0 state which is growing with the cluster size may be the cause of a larger number of degrees of freedom.
