This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will assist the Department of Chemistry at University of North Carolina at Chapel Hill to acquire a step-scan FTIR spectrometer. This equipment will enhance research in a number of areas including the following: (1) the application of time-resolved infrared spectroscopy (TRIR) to short lived excited state species and intermediates in the photophysics of transition metal-polypyridyl systems and (2) the application of TRIR and rotationally-resolved IR to the processes of aerosol nucleation and combustion. A Fourier transform infrared (FT-IR) spectrometer and a time-resolved IR (TRIR) can provide important information about molecular and electronic structure of short-lived transient intermediates. Their use may enable breakthroughs in our understanding of the properties of reactivity and non-reactivity of molecules..

该奖项由化学研究仪器和设施 （CRIF）计划将协助大学化学系 位于查佩尔山的北卡罗来纳州，以获取步进扫描FTIR光谱仪。 这些设备将加强若干领域的研究，包括 时间分辨红外光谱技术的应用 （TRIR）的短寿命激发态物种和中间体， 过渡金属-多吡啶体系的电子物理和（2） TRIR和旋转分辨IR在化学过程中的应用 气溶胶成核和燃烧。 傅里叶变换红外光谱仪和时间分辨红外光谱仪 （TRIR）可以提供有关分子和电子的重要信息 短寿命瞬态中间体的结构。它们的使用可以使 我们对反应性的理解上的突破， 分子的非反应性。
