State-resolved Spectroscopy and Dynamics of Chemical Transients

在这个由化学部门实验物理化学项目资助的奖项中，科罗拉多大学博尔德分校的David Nesbitt教授和他的同事将继续他们的研究，以促进高活性瞬态化学物质的实验和理论之间的基准测试。Nesbitt教授的分子光谱学研究项目将扩展喷气冷却自由基/分子离子、金属/金属离子簇、单分子显微镜和动力学的知识基础。利用狭缝放电光谱仪对射流冷却的分子离子进行高灵敏度红外光谱分析是今后研究的重点。另外一个重点将是脉冲激光器与狭缝射流扩展和高分辨率直接吸收激光方法的结合，以提供对新型有机金属、金属/吸附物和金属离子/溶剂物种的高分辨率红外通道。Nesbitt教授的团队还将开发和利用新的时间、颜色和偏振荧光显微镜功能，以探索分离生物分子的复杂分子内动力学。最终，这些实验应该为从大气化学到工业应用和生化催化等一系列化学转化提供最重要的基础新知识。这项研究将与博士后助理、研究生和本科生一起进行，包括女性和代表性不足的少数民族。研究人员还将通过“CU奇才”项目参与向中小学生的推广工作。

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.
