Energy Relaxation Studies Using Infrared Spectroscopy on Molecular Beams (Chemistry)

瓦茨教授是范德华分子红外吸收光谱学的先驱。他过去的工作包括实验和理论研究。在目前的研究中，他将继续和扩展这些研究，以提供关于分子相互作用、势能面、分子内能量转移和振动动力学的信息。需要这些信息来测试碰撞和凝聚相性质的计算，以及描述化学反应是如何发生的。在不久的将来，瓦茨博士将使用F中心激光和二氧化碳激光测量小的、弱束缚的范德华星系团和强关联星系团的高分辨率红外光谱，用飞行时间质谱仪测量红外诱导星系团碎裂的角分布和能量，对He/Hf系统的状态分辨微分散射测量进行了理论和实验研究。

Professor Watts is a pioneer in infrared absorption spectroscopy of van der Waals molecules. His past work has included both experimental and theoretical studies. In the current research, he will continue and extend these investigations to provide information about molecular interactions, potential energy surfaces, intramolecular energy transfer, and vibrational dynamics. This information is needed to test calculations of collisional and condensed phase properties as well as to describe how chemical reactions occur. In the near future, Dr. Watts will measure the high resolution infrared spectra of both small, weakly bound,van der Waals and strongly associated clusters using F-center and carbon dioxide lasers, the angular distributions and energetics of infrared induced cluster fragmentation by time-of-flight mass spectrometry, and theoretical and experimental investigations of state resolved differential scattering measurements on the He/HF system.
