Applying femtosecond pump–probe spectroscopy at different wavelengths we demonstrate that for the indole molecule an efficient coupling does not exist between the initially excited ππ* state and the adjacent higher lying π σ * state. This resul

Two-photon excitation with femtosecond laser pulses in the spectral range 240-250 nm was used to prepare vapor phase H(2)O and D(2)O in the C (1)B(1) and D (1)A(1) states. Both states are predissociated via the B (1)A(1) state, forming excited OH/OD(

Neutral ammonia clusters (NH3)m are photo-excited to the electronic \(\) state by a deep UV femtosecond laser pump pulse. Within a few hundred femtoseconds a significant fraction of the clusters rearrange to form an H-transfer state (NH3)m-2NH4(3s)NH
