✦ Synopsis

The relaxation of HCI(v) in H20-HCI collisions for v= 1-10 is studied using classical trajectory techniques at thermal collision energies. In the presence of strong attraction, the collision partners form a complex, in which intramolecular energy transfer takes place efficiently. For HC1 (v= 0-3 ) many complexes survive for several picoseconds, but for HCI (v> 3) most of the collisions last for about 1 ps or less. On redissociation, the major part of the energy released by HC1 (v) deposits in the HC1 rotations. The rest transfers into translation. The extent of vibrational energy transfer increases linearly with increasing v.
