With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Ursinus College will acquire a Mossbauer (MB) spectrometer. Faculty at St. Joseph's University, SUNY-Stony Brook, Texas A&M University and the University of Delaware will also carry out research using this spectrometer. Mossbauer investigations range from studies of small molecule iron compounds to the exploration of novel iron sites in proteins. Projects will focus on analyzing hyperfine spectra to determine the number of distinct iron sites in the sample, their oxidation and spin state and magnetic behavior. These parameters will be interpreted in terms of electronic models, allowing the investigators to make predictions of molecular structure and function. Owing to the great expansion of iron bio-inorganic chemistry, Mossbauer spectrometers are now more frequently found in academic Chemistry departments. The establishment of the MB spectroscopy lab at Ursinus College will benefit the chemical research in the Philadelphia region, involving scientists in Physics, Chemistry and Biochemistry. Because of the possible applications of MB spectroscopy in the analysis of a variety of biological samples and chemical compounds, the presence of such instrumentation should prove attractive for students in a variety of research programs. Thus the training potential is significant. The highly interdisciplinary character of the projects indicates a strong impact in fields ranging from synthetic and physical inorganic chemistry to spectroscopy of proteins.

在主要研究仪器（MRI）计划的支持下，乌尔西诺学院化学系将获得一台穆斯堡尔（MB）光谱仪。 圣约瑟夫大学、纽约州立大学石溪分校、德克萨斯农工大学和特拉华州大学的教师也将使用这种光谱仪进行研究。 穆斯堡尔谱的研究范围从小分子铁化合物的研究到蛋白质中新铁位点的探索。 项目将侧重于分析超精细光谱，以确定样品中不同铁位点的数量，它们的氧化和自旋状态以及磁性行为。 这些参数将根据电子模型进行解释，使研究人员能够预测分子的结构和功能。 由于铁的生物无机化学的极大扩展，穆斯堡尔谱仪现在更经常地出现在学术化学系。 在Ursinus学院建立MB光谱实验室将有利于费城地区的化学研究，涉及物理，化学和生物化学的科学家。 由于MB光谱在分析各种生物样品和化合物中的可能应用，这种仪器的存在应该证明对各种研究项目的学生有吸引力。 因此，培训潜力很大。 这些项目的高度跨学科性质表明了从合成和物理无机化学到蛋白质光谱学等领域的强烈影响。
