MRI: Acquisition of a Nanosecond Laser System

卡拉马祖学院化学系将获得来自主要研究仪器(MRI)项目的这一奖项，该学院将获得纳秒激光系统。研究活动将包括测量挥发性有机金属亚硝基光解的矢量关联，特别是角动量与速度之间的关联以及跃迁偶极子与速度之间的关联。这些实验结果将揭示Jahn-Teller扭曲在激发态金属亚硝基化合物中的作用，并可能揭示金属-NO解离的时间尺度。这些结果可以扩展到理解生物系统中的化学气相沉积和非金属相互作用。这所以本科为主的院校的学生研究人员将参与这些研究。纳秒激光提供超快的相干可见光或红外光脉冲，使研究人员能够获得关于快速发生的化学反应的重要信息。它的使用可能会使我们对活性和非活性分子的性质的理解有所突破。这些研究将对材料化学和生物化学产生影响。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Kalamazoo College will acquire a nanosecond laser system. The research activities will involve measurement of vector correlations in the photodissociation of volatile organometallic nitrosyls, especially the correlations between angular momentum and velocity and between the transition dipole and velocity. The results obtained in these experiments will reveal the role of Jahn-Teller distortions in excited organometallic nitrosyl compounds and may reveal the timescale for metal-NO dissociation. These results can be extended into understanding chemical vapor deposition and NO-metal interactions in biological systems. Student researchers at this primarily undergraduate institution will participate in these studies. A nanosecond laser provides ultrafast pulses of coherent visible or infrared light, which enables researchers to obtain important information about fast occurring chemical reactions. Its use may enable breakthroughs in our understanding of the properties of reactive and nonreactive molecules. These studies will have an impact in materials chemistry and biochemistry.
