U.S. - France Cooperative Research: Generation and Applications of Tunable Vacuum Ultraviolet Laser Light

9314377休斯敦两年奖支持美国-法国在物理化学方面的合作研究，由康奈尔大学的保罗·休斯顿和位于梅顿的巴黎天文台的弗朗索瓦·罗斯塔斯共同完成。他们的研究目标是开发一种波长范围为110-170 nm的可调谐真空紫外线(VUV)激光光源，并将其应用于二氧化碳(CO2)的光谱和解离动力学。激光被认为是研究二氧化碳(CO2)在低波长下光解为碳-氧和氧的选择和必要的光源。这位美国研究人员为这次合作带来了分子动力学方面的广泛专业知识，特别是在光化学激光解离分子领域。法国研究人员在具有天体物理重要性的双原子和小多原子分子的真空紫外光谱学方面的专业知识补充了这一点。二氧化碳是大气和星际的重要组成部分。在地球大气层中，它对热平衡有深远的影响。它也是火星和金星大气的主要成分。该项目将促进我们对它的光学性质和光化学过程的理解。***

9314377 Houston This two year award supports U.S.-France cooperative research in physical chemistry between Paul Houston, Cornell University, and Francois Rostas of the Paris Observatory in Meudon. The objective of their research is to develop a tunable vacuum ultraviolet (VUV) laser light source for the wavelength range 110-170 nm and its application to spectroscopy and dissociation dynamics of carbon dioxide (CO2). The laser is considered the light source of choice and necessity for investigating photo- dissociation of carbon dioxide (CO2) into carbon-oxygen and oxygen at low wavelengths. The U.S. investigator brings to this collaboration extensive expertise in molecular dynamics, especially in the area of photo-chemically laser dissociated molecules. This is complemented by the French investigator's expertise in VUV spectroscopy of diatomic and small polyatomic molecules of astrophysical importance. Carbon dioxide is an important atmospheric and interstellar constituent. In the earth's atmosphere, it has a profound effect on the thermal balance. It is also the principal constituent of the atmosphere of Mars and Venus. This project will advance our understanding of its optical properties and its photochemical processes. ***
