Abstract

We studied the time evolution of the wave packet formed by the excitation of the Ba⋯FCH₃ complex with a 120 fs laser pulse at 745 nm to its electronic Ã' state which is repulsive at the ground state geometry and decays to Ba and CH₃F fragments. By applying probe pulses with different wavelengths of 400 and 267 nm, respectively, we observed strongly different time dependences of the pump-probe signals for the BaF⁺ and Ba⁺ ions determined by the Franck-Condon windows available in both cases. The experimental results are qualitatively confirmed by theoretical studies based on ab initio calculations of the corresponding potential energy surfaces.
