This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at Iowa State University in the purchase of a quadrupole mass spectrometer. The faculty members whose research is dependent upon mass spectroscopy will greatly benefit from the acquisition of this instrument. Research projects to be carried out with this instrument include: analysis of high and low molecular weight polar compounds, along with liquid sample introduction capability; the development of new synthetic methods for the synthesis of medicinally useful compounds; studies of free radical and electron transfer processes; characterization of organometallic complexes; the study of molecular recognition; and new pathways for the total synthesis of natural products. A high resolution mass spectrometer is an instrument used to measure the precise molecular weight of a molecular ion. This information is an important piece of data used to help determine the atomic composition and, sometimes, the molecular geometry of a molecule. It is one of the essential tools needed to learn the detailed structure of newly synthesized molecules.

这份来自化学研究仪器和设施项目的合同将帮助爱荷华州立大学化学系购买一台四极质谱计。研究依赖于质谱的教职员工将从该仪器的获得中受益匪浅。该仪器的研究项目包括：高分子量和低分子量极性化合物的分析，以及液体样品导入能力；药用化合物合成新方法的发展；自由基和电子转移过程的研究；有机金属配合物的表征；分子识别的研究；以及天然产物全合成的新途径。高分辨率质谱仪是一种用来精确测量分子离子分子量的仪器。这些信息是一个重要的数据，用于帮助确定原子组成，有时，分子的分子几何形状。它是了解新合成分子的详细结构所需的基本工具之一。
