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. ??

INT 9531458 Gerber这个由美国加州大学欧文分校的R.Benny Gerber和布拉格海罗夫斯基物理化学研究所的Pavel Jungwirth共同开展的美国-捷克研究项目，将研究多体系统的化学动力学，目的是表征范德墙和氢键团簇中的系统。其目的是利用美国参与者和布拉格小组在电子结构计算中的量子动力学优势来研究三个具体主题：1)嵌入大的Ar团簇中的碘的光解离、猝灭和复合的光谱和动力学；2)水中氯原子在电子从水合氯离子中光剥离后的动力学；以及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相现象的基本知识。这个理论物理化学项目通过使美国和东欧的顶尖专家能够将互补的人才结合在一起，并在共同感兴趣和能力的领域汇集研究资源，实现了促进科学知识的计划目标。?？
