Resonant Four-Wave Mixing Probes of Molecular Structure and Dynamics

耶鲁大学的Patrick Vaccaro教授将在化学学部的物理化学项目中进行一系列结合简并四波混频和受激发射泵送方法的实验。研究了一氧化二硫和异氰原的异构化化学。对丙二醛中质子转移的状态特异性研究也将进行。重点将放在识别和表征任何振动模式的选择性，伴随着分子内的化学键重排。这项研究是在分子结构和动力学的广泛领域。它的目的是探索化学转化的潜在动力。从这些振动激发的多原子物种实验中获得的信息将提供对化学中起关键作用的单分子过程的见解，包括异构化和氢迁移。

In this project in the Physical Chemistry program of the Chemistry Division, Professor Patrick Vaccaro of Yale University will perform a series of experiments which combine the methods of Degenerate -Four-Wave-Mixing and Stimulated-Emission-Pumping. The chemistry of isomerization will be studied on disulfur monoxide and isocyanogen. A state-specific study of the proton transfer in malonaldehyde will also be carried out. Emphasis will be placed upon the identification and characterization of any vibrational mode selectivity that accompanies intramolecular rearrangement of chemical bonds. This research is in the broad area of molecular structure and dynamics. Its purpose is to explore the underlying impetus for chemical transformations. Information obtained from these experiments on vibrationally excited polyatomic species will provide insight into unimolecular processes which play a critical role in chemistry, including isomerization and hydrogen migration.
