State-resolved Spectroscopy and Dynamics of Chemical Transients

在这个奖项，由化学系实验物理化学计划资助，科罗拉多大学博尔德分校的大卫·内斯韦尔教授和他的同事将继续他们的研究，以促进高反应性，瞬态化学物种的实验和理论之间的基准测试。 教授Nesperson的分子光谱学的研究计划将扩大喷射冷却自由基/分子离子，金属/金属离子簇，和单分子显微镜和动力学的知识基础。 工作的一个主要重点将是利用狭缝放电光谱仪的高灵敏度红外（IR）光谱的喷射冷却分子离子。 另一个重点将是结合脉冲激光与狭缝射流膨胀和高分辨率直接吸收激光方法，以提供高分辨率的红外访问新的有机金属，金属/吸附物，和金属离子/溶剂物种。 Nesperson教授的研究小组还将开发和利用新的时间、颜色和偏振荧光显微镜功能，用于探索孤立生物分子的复杂分子内动力学。最终，这些实验将为从大气化学到工业应用和生物化学催化等一系列化学转化提供至关重要的基础新知识。 这项研究将与博士后助理，研究生和本科生，包括妇女和代表性不足的少数民族进行。 研究人员还将通过“CU奇才”计划参与对小学和中学生的推广工作。

In this award, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Professor David Nesbitt of the University of Colorado at Boulder and his associates will continue their investigations to facilitate benchmark tests between experiment and theory of highly reactive, transient chemical species. Professor Nesbitt's research program in molecular spectroscopy will expand the knowledge base of jet-cooled radicals/molecular ions, metal/metal ion clusters, and single molecule microscopy and kinetics. A major focus of the work will be to exploit the slit discharge spectrometer for high sensitivity infrared (IR) spectroscopy of jet-cooled molecular ions. An additional focus will be the combination of pulsed lasers with slit jet expansions and high resolution direct absorption laser methods to provide high resolution IR access to novel organometallic, metal/adsorbate, and metal ion/solvent species. Professor Nesbitt's group will also develop and exploit novel time, color and polarization fluorescence microscopy capabilities for exploring complex intramolecular dynamics of isolated biomolecules.Ultimately, these experiments should provide fundamental new knowledge of utmost importance in a host of chemical transformations, ranging from atmospheric chemistry to industrial applications and biochemical catalysis. This research will be conducted with post-doctoral associates, graduate students, and undergraduate students, including women and underrepresented minorities. The researchers will also be involved in outreach efforts to elementary and middle school students through the 'CU Wizards' program.
