Acquisition of a Laser Flash Photolysis System

这份来自化学研究仪器项目的合同将帮助位于韦恩堡的印第安纳-普渡大学化学系购买激光设备。该设备将用于以下研究活动：溶液中铜(I)配合物的光化学和光物理，多核钌（II）配合物的光物理研究，使用ıNi(III) （cyclam）催化二氧化硫的自氧化！： 8-取代1-萘基羰基：卤代溴羰基生成杂萘酰基化合物的新机制的阐明和观察。激光发射出一束狭窄的、连贯的、强大的、几乎单色的电磁辐射。这种辐射将允许研究人员在紫外线、可见光和近红外区域的光活性系统中产生短寿命的化学中间体。该系统的动能光谱仪部分将允许操作人员测量这些中间体的光学发射或吸光度，作为时间的函数。激光在化学中被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。激光在光学、通信和工程方面也很有用。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at Indiana - Purdue University at Ft. Wayne purchase laser equipment. This equipment will be used in the following research activities: photochemistry and photophysics of copper (I) complexes in solution, photophysical studies of polynuclear ruthenium (II) complexes, catalysis of the autoxidation of sulfur dioxide using ıNi(III) (cyclam)!: elucidation of a novel mechanism, and generation and observation of heteroacenaphthene ylides via 8-substituted 1-naphthyl carbenes: halonium ylides. Lasers emit a narrow beam of coherent, powerful and nearly monochromatic electromagnetic radiation. This radiation will allow the researchers to generate short-lived chemical intermediates in photoactive systems in the ultraviolet, visible, and near-infrared regions. The kinetic spectrometer part of the system will permit the operators to measure the optical emission or absorbance of these intermediates, as a function of time. Lasers are 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.
