Purchase of an UV-IR Picosecond/Femtosecond Laser Facility

该奖项来自化学研究仪器和设施(CRIF)计划和学术研究基础设施(ARI)计划，将帮助普林斯顿大学化学系获得短脉冲激光系统。该设备将加强以下领域的研究：(1)蛋白质和卟啉激发态的结构和动力学(2)液氦团簇上/中的时间分辨化学动力学和光谱(3)分子内振动能量重新分配的含时反斯托克斯拉曼研究(4)化学动力学的相干控制(5)生物和固态体系中的电子转移研究，以及(6)两个电子转移过程。可调谐激光可以提供有关化学反应的重要信息。它的使用可能使我们对分子的反应性和非反应性的性质的理解有所突破。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program and the Academic Research Infrastructure (ARI) Program will assist the Department of Chemistry at Princeton University acquire a short pulse laser system . This equipment will enhance research in a number of areas including the following: (1) structure and dynamics of proteins and porphyrin excited states (2) time resolved chemical dynamics and spectroscopy on/in liquid helium clusters (3) time dependent anti-Stokes Raman study of intramolecular vibrational energy redistribution (4) coherent control of chemical dynamics (5) electron transfer studies in biological and solid state systems, and (6) two electron charge transfer processes. A tunable laser can provide important information about chemical reactivity. Its use may enable breakthroughs in our understanding of the properties of reactivity and nonreactivity of molecules.
