U.S.-Czech Chemistry Research on Ultrafast Dynamics and Spectroscopy in Large Molecular Clusters

这个由加州大学欧文分校的R. Benny Gerber和布拉格Heyrovsky物理化学研究所的Pavel Jungwirth合作的美国-捷克研究项目，将研究多体系统的化学动力学，以表征诸如van der Walls和氢键团簇的系统。目的是利用美国参与者在量子动力学方面的优势和布拉格小组在电子结构计算方面的优势来研究三个具体主题：1)嵌入在大氩团簇中的碘的光解、猝灭和重组的光谱学和动力学；2)水中氯原子与水合氯离子电子光分离后的动力学；3)光激发氢键团簇中的拉曼光谱和氢原子动力学。这些结果有望有助于我们对分子团簇和相关凝聚态现象的基本认识。该理论物理化学项目通过使美国和东欧的领先专家在共同感兴趣和能力的领域结合互补的人才和集中研究资源，实现了推进科学知识的计划目标。?？

INT 9531458 Gerber This U.S.-Czech research project between R. Benny Gerber of the University of California, Irvine, and Pavel Jungwirth of the Heyrovsky Institute of Physical Chemistry, Prague, will examine the chemical dynamics of many-body systems for the purpose of characterizing systems such as those in van der Walls and hydrogen bonded clusters. The intent is to employ the strengths in quantum dynamics of the U.S. participants and those of the Prague group in electronic structure calculations to study three specific topics: 1) Spectroscopy and dynamics of photodissociation, quenching and recombination of iodine embedded in large argon clusters; 2) the dynamics of a chlorine atom in water following electron photodetachment from hydrated chloride ions; and 3) Raman spectra and hydrogen atom dynamics in photoexcited hydrogen bonded clusters. Results are expected to contribute to our basic knowledge of molecular clusters and related condensed phase phenomena. This project in theoretical physical chemistry fulfills the program objective of advancing scientific knowledge by enabling leading experts in the United States and Eastern Europe to combine complementary talents and pool research resources in areas of mutual interest and competence. ??
