Abstract:

Many chemical and physical changes depend on the transfer of energy that occurs in an encounter between molecules. In recent years, new sophisticated experimental and theoretical techniques have addressed fundamental questions of energy transfer between individual quantum states in bimolecular collisions. Many processes are found to be state-specific, and the effects of different forms of energy are not equivalent. For example, some chemical reactions may be promoted more by vibrational than translational energy, or vice versa, and electronic state transfer may be more affected by rotation than by vibration. From a more applied standpoint, we are unable to predict details of energy transfer that might be needed to model the behavior of some practical system, outside the immediate regime of prior measurements.
