Purchase of a Step-Scan FTIR Spectrometer and Accessories

这份来自化学研究仪器和设施（CRIF）项目的合同将帮助北卡罗来纳大学教堂山分校的化学系获得一台阶梯扫描FTIR光谱仪。该设备将加强在以下几个领域的研究：(1)应用时间分辨红外光谱（TRIR）对过渡金属-聚吡啶体系光物理中的短寿命激发态物质和中间体的研究；(2)应用TRIR和旋转分辨红外光谱对气溶胶成核和燃烧过程的研究。傅里叶变换红外光谱仪（FT-IR）和时间分辨红外光谱仪（TRIR）可以提供有关短寿命瞬态中间体分子结构和电子结构的重要信息。它们的使用可能使我们对分子的反应性和非反应性的理解取得突破。

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..
