The Applicant seeks NSERC support to reinstate an inoperative laser Raman spectrometer that resulted when the system's laser recently failed, to upgrade the system's computer and operating software and to replace a faulty spectrometer power supply. Raman spectroscopy is a fundamental technique that examines molecular vibrations by analyzing the light scattered by a sample of a chemical compound when it is irradiated by laser light. These data can be used to identify and characterize the molecular structures of many materials. This instrument is essential to all of the Applicant's research programs. These include the search for new compounds with new or rare oxidation states, bonding and structures. Many of these compounds are fluorine compounds of the non-metallic and metallic elements of the Periodic Table and are extremely difficult to synthesize and manipulate. Such fragile compounds are at the limits of what is chemically possible and their oftentimes unusual combinations of the elements have unique properties and/or constitute systems that test the limits of and help to refine our current theories and models of electronic structure and bonding between atoms.

申请人寻求 NSERC 支持以恢复因系统激光器最近发生故障而导致的无法工作的激光拉曼光谱仪、升级系统的计算机和操作软件以及更换有故障的光谱仪电源。拉曼光谱是一项基本技术，通过分析化合物样品在激光照射下散射的光来检查分子振动。这些数据可用于识别和表征许多材料的分子结构。该仪器对于申请人的所有研究项目都是必不可少的。其中包括寻找具有新的或稀有的氧化态、键合和结构的新化合物。这些化合物中有许多是元素周期表中非金属和金属元素的氟化合物，并且极难合成和操作。这些脆弱的化合物处于化学可能的极限，它们通常不寻常的元素组合具有独特的性质和/或构成测试极限的系统，并有助于完善我们当前的电子结构和原子间键合的理论和模型。
