Abstract
We have in recent years studied the photolysis of the triiodide ion in solution, using femtosecond laser flash photolysis. The impulsive nature of the excitation sets the dissociation in motion in the form of a coherent wavepacket, and induces coherent vibration in the symmetric stretching vibration on the ground potential of the J3. Using photoselective transient transmission as a tool, ail of the important modes of motion in the diatomic ionic product are directly followed in real time after dissociation, including vibrational coherence induced by the kinematics of the process of bond fission.
