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.

在化学系物理化学项目的这个项目中，耶鲁大学Patrick Vaccaro教授将进行一系列结合简并四波混合和受激发射泵浦方法的实验。 研究一氧化二硫和异氰的异构化化学。 还将对丙二醛中的质子转移进行国家特定的研究。 重点将放在伴随化学键分子内重排的任何振动模式选择性的识别和表征上。 这项研究涉及分子结构和动力学的广泛领域。 其目的是探索化学转化的潜在动力。 从这些关于振动激发多原子物种的实验中获得的信息将有助于深入了解在化学中发挥关键作用的单分子过程，包括异构化和氢迁移。
