This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at Ohio State University purchase laser equipment. This equipment will be used in the following research activities: 1) Time correlated single photon counting (TCSPC) for picosecond fluorescence lifetime measurements. 2) Picosecond and femtosecond UV/Visible transient absorption measurements. 3) Picosecond transient resonance Raman measurements and picosecond transient IR absorption measurements. 4) Nonlinear optical (NLO) characterization of materials using degenerate four wave mixing (DFWM) and the optical Kerr effect (OKE). Lasers emit a narow beam of coherent, powerful and nearly monochromatic electromagnetic radiation. This radiation is used in Chemistry to study a broad range of subjects, from the dynamics of proteins and nucleic acids to photoelectron transfer processes, and from interfacial chemistry to picosecond pulse shaping. Lasers are also useful in optics, communications, and engineering.

化学研究仪器计划的这一奖项将帮助俄亥俄州立大学化学系购买激光设备。 该设备将用于以下研究活动：1）用于皮秒荧光寿命测量的时间相关单光子计数（TCSPC）。 2) 皮秒和飞秒紫外/可见瞬态吸收测量。 3) 皮秒瞬态共振拉曼测量和皮秒瞬态红外吸收测量。 4) 使用简并四波混频 (DFWM) 和光学克尔效应 (OKE) 对材料进行非线性光学 (NLO) 表征。 激光器发射出一束相干、强大且近乎单色的窄电磁辐射。 这种辐射在化学中用于研究广泛的学科，从蛋白质和核酸的动力学到光电子转移过程，从界面化学到皮秒脉冲整形。 激光器在光学、通信和工程领域也很有用。
