摘要

We have used femtosecond impulsive excitation to time-resolve the vibrational motions following the excitation of the optical intervalence charge transfer transition in a quasi-one-dimensional molecular solid, the mixed-valence metal-halide linear chain complex [Pt(en)_2][Pt(en)_2Br_2]·(PF_6)_4 (en = ethylenediamine, C_2H_8N_2). Wavelength-resolved measurements reveal an induced absorption signal assigned to the formation of the self-trapped exciton that is strongly modulated by vibrational wavepacket oscillations originating on both the ground and excited electronic states. The ground-state response, which includes the fundamental chain axis symmetric stretch frequency and its harmonics, is discussed in terms of resonantly enhanced impulsive stimulated Raman excitation of a strongly coupled electron-phonon system.
