High Resolution Spectroscopy Facility

激光为化学家提供了一种精细的探针，用于各种研究，如获得分子束的极高分辨率光谱，研究电子激发态下分子运动的动力学，以及研究DNA对紫外光的反应。华盛顿大学化学系将利用由化学共享仪器计划和仪器与仪器开发计划联合资助的这一奖项，帮助获得用于高分辨率光谱设施的激光仪器。此次收购将加强的研究领域包括：1)范德华团簇的结构和衰减动力学2)不同尺寸h键团簇的振动和能带形状3)小团簇的光解离途径4)状态选择散射5)结合势面和非结合势面分子非定态的光谱学研究6)超卷曲dna的紫外光动态光散射研究。

Lasers afford the chemist with a delicate probe for such diverse studies as obtaining extremely hih-resolution spectra of molecular beams, studying the dynamics of molecular motions in electronically excited states and studying how DNA's respond to ultraviolet light. The Department of Chemistry of the University of Washington will use this award, joint-funded by the Chemistry Shared Instrumentation Program and the Instrumentation and Instrumentation Development Program, to help acquire laser instrumentation for a high-resolution spectroscopy facility. The areas of research that will be enhanced by the acquisition include: 1) Structures and decay dynamics of van der Waals clusters 2) Vibrations and band-shapes of H-bonded clusters of different size 3) Photodissociation pathways of small clusters 4) State-selected scattering studies 5) Spectroscopy of non-stationary states of molecules on bound and unbound potential surfaces 6) Dynamic light scattering of supercoiled DNAs using ultraviolet light.
