有了这项来自主要研究仪器（MRI）计划的奖项，康奈尔大学化学系将获得一台高分辨率台式气相色谱质谱仪（GC/MS）。这种新的光谱仪将使国家科学基金会资助的核心研究人员能够在以下方面开展研究：a）阐明碳氢化合物燃烧的化学机理; B）非统计动力学在活性中间体行为中的作用; c）将大气氮固定为增值产品; d）在合成复杂分子目标中寻找贵金属的替代物; f）有机锂试剂的结构和机理研究; g）从昆虫病原真菌、植物病原细菌和高等植物中发现新的天然产物; h）定点分离催化; i）分离和表征具有生物学意义的节肢动物天然产物; j）开发新的、操作简单且灵活的合成方法，其与复杂的化学合成相容。来自整个校园的一大群其他研究人员也将在涉及生物有机化学，化学生态学，碳水化合物化学，脂质膜，材料科学和有机/有机金属合成的研究项目中使用所需的光谱仪。简而言之，所要求的光谱仪将使许多研究人员能够表征天然存在或新产生的物质，确定分子或分子片段的分子质量，并确定材料的组成。气相色谱-质谱联用（GC/MS）是一种非常强大的技术，用于复杂混合物的分离和分析。 使用所要求的光谱仪的研究结果将对有机/有机金属化学、聚合物化学、化学生物学、天然产物化学、催化和材料化学产生影响。.

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Cornell University will acquire a high-resolution bench-top gas chromatograph mass spectrometer (GC/MS). This new spectrometer will allow a core of NSF-funded researchers to carry out research in: a) elucidating the chemical mechanisms underlying hydrocarbon combustion; b) the role of nonstatistical dynamics in the behavior of reactive intermediates; c) fixation of atmospheric nitrogen into value-added products; d) finding surrogates for precious metals in the synthesis of complex molecular targets; e) developing new synthetic strategies for producing polymeric materials of defined molecular structure; f) structural and mechanistic studies of organolithium reagents; g) discovery of novel natural products from insect pathogenic fungi, plant pathogenic bacteria, and higher plants; h) site-isolated catalysis; i) isolation and characterization of biologically significant arthropod natural products; j) developing new, operationally simple, and flexible synthetic methods, which are compatible with complex chemical syntheses. A large group of other researchers from across the campus will also use the requested spectrometer in research projects involving bioorganic chemistry, chemical ecology, carbohydrate chemistry, lipid membranes, materials science, and organic/organometallic synthesis. In short, the requested spectrometer will allow many researchers to characterize naturally occurring or newly created substances, to determine the molecular mass of molecules or molecular fragments, and determine the composition of materials. Gas chromatograph with mass spectrometric detection (GC/MS) is an extremely powerful technique used for the separation and analysis of complex mixtures. The results from studies using the requested spectrometer will have an impact on organic/organometallic chemistry, polymer chemistry, chemical biology, natural product chemistry, catalysis, and materials chemistry. .
