We have directly time resolved the lattice motions associated with the formation of the self-trapped exciton in the quasi-one-dimensional system [Pt(en)₂][Pt(en)₂Br₂]̇(PF₆)₄ ( en = ethylene-diamine, C₂H₈N₂), using femtosecond impulsive excitation techniques. A strongly damped, low-frequency wave packet modulation at ∼110cm^-1 accompanies the formation of the self-trapped exciton on a ∼200fs time scale following excitation of the intervalence charge-transfer transition. Coherent oscillations at the ground state vibrational frequency and its harmonics are also detected.
