US-France Cooperative Research: Towards a Universal Water Force Field from VRT Spectra

0003807Saykally这项为期三年的美法化学合作研究奖的获得者是加州大学伯克利分校的Richard J. Saykally和法国蒙彼利埃第二大学的Claude LeForestier。他们合作的目标是构建和提供一个准确的、普遍适用的力场来描述液体和固体水。伯克利小组将进行激光振动旋转隧穿（VRT）红外（IR）腔对水团簇的实验研究。蒙彼利埃小组将专注于水二聚体和三聚体光谱的理论描述。美国小组为这次合作带来了太赫兹VRT和红外光谱的实验能力。这是由法国在维格纳伪谱方法和振动预解理论专业知识补充。该奖项代表了美国国家科学基金会和法国国家科学研究中心（CNRS）联合提案的美方。美国国家科学基金会将支付美国研究人员和研究生的旅费和生活费。法国科学研究中心将支持法国研究人员访问美国。这次合作解决了一个重要的科学问题——水分子间电位的精确测定。该项目将推进对水力场的基本认识。

0003807SaykallyThis three-year award for U.S.-France cooperative research in chemistry involves Richard J. Saykally of the University of California at Berkeley and Claude LeForestier at the Universite de Montpellier II in Montpellier, France. The objective of their collaboration is to construct and deliver an accurate and generally applicable force field for describing liquid and solid water. Experimental studies of water clusters by laser vibration rotation tunneling (VRT) infrared (IR) cavity will be conducted by the Berkeley group. The Montpellier group will focus on theoretical descriptions of water dimer and trimer spectra. The US group brings to this collaboration experimental capabilities in terahertz VRT and IR spectroscopy. This is complemented by French theoretical expertise in Wigner pseudospectral method and vibrational predissociation. This award represents the US side of a joint proposal to NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigator and graduate students. The CNRS will support the visits of French researchers to the United States. The collaboration addresses an important scientific question - the accurate determination of water's intermolecular potential. The project will advance fundamental understanding of the water force field.
