Dr. Robert Parson is supported by a grant from The Theoretical and Computational Chemistry Program to study the dynamics of energy transfer which occurs in molecular collisions. Collision-induced energy transfer plays an important role in many physical and chemical problems such as population inversion in chemical lasers, and the spectroscopy of stellar atmospheres. Dr. Parson will study collisions between rare-gas atoms and highly rotationally excited diatoms, emphasizing the strong "quasiresonant" correlation between vibrational and rotational energy tranfer that has been seen in recent experiments. A collision-induced resonance theory for the final state distributions will be developed and tested. Subsequent studies will extend this approach to diatom-diatom collisions. Studies of polyatomic collisions will emphasize the breakdown of the distinction between vibrational and rotational energy transfer.

罗伯特·帕森博士得到了理论和计算化学项目的资助，用于研究分子碰撞中发生的能量转移的动力学。碰撞诱导的能量转移在许多物理和化学问题中起着重要的作用，如化学激光中的布居反转和恒星大气的光谱。帕森博士将研究稀有气体原子和高度旋转激发的硅藻之间的碰撞，强调振动和旋转能量传递之间的强“准共振”相关性，这是最近的实验中看到的。将开发和测试用于终态分布的碰撞诱导共振理论。随后的研究将把这种方法扩展到硅藻-硅藻碰撞。对多原子碰撞的研究将强调打破振动和旋转能量转移之间的区别。
