Nonlinear Phenomena in Molecular Energy Transfer

图尔盖·乌泽教授得到了理论和计算化学计划的资助，继续他对孤立分子和表面上的能量转移过程的研究。这项研究对于帮助化学家理解激光光解离和激光表面光解吸的物理过程具有重要意义。Uzer的理论和计算工作涉及分子内能量流动的基本原理，不可分离振子系统的动力学和量子化，分子内动力学和单分子反应的建模，以及表面-吸附界面的微观动力学。乌泽尔发展了一种新的“不对称顶映射”程序，他将用它来研究局域化机制，并推断分子内瓶颈附近量子态的结构和系统学。他将把这种类型的分析应用于过氧化氢和烷基过氧化氢的光解离研究。氢气在氧化铝上的分子特定光解吸动力学和可行性将被研究。最后，他还将研究覆盖影响表面吸附松弛的微观机制。

Professor Turgay Uzer is supported by a grant from The Theoretical and Computational Chemistry Program to continue his studies of energy transfer processes in isolated molecules and on surfaces. This research is important in helping chemists to understand the physical processes involved in laser photodissociation, and laser photodesorption from surfaces. Uzer's theoretical and computational work concerns the fundamentals of intramolecular energy flow, the dynamics and quantization of nonseparable oscillator systems, modeling of intramolecular dynamics and unimolecular reactions, and microscopic dynamics at the surface-adsorbate interface. Uzer has developed a novel "asymmetric top mapping" procedure which he will use to investigate the mechanism of localization and to infer the structure and systematics of quantum states near intramolecular bottlenecks. He will apply this type of analysis to the study of the photodissociation of hydrogen peroxide and alkyl hydroperoxides. The dynamics and feasibility of molecule specific photodesorption will be investigated for hydrogen on aluminum oxide. Finally, he will also investigate the microscopic mechanisms by which coverage influences adsorbate relaxation on surfaces.
