With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Akron will acquire an Electron Paramagnetic Resonance (EPR) Spectrometer. Research projects to benefit from the EPR include studies on such paramagnetic materials as 1) metallo-enzyme models; 2) novel organometallic materials; 3) MRI contrast agents; 4) porphyrin complexes; 5) biomaterials; 6) conducting polymers; 7) silyl radicals; 8) powder coatings; 9) catalysts; and 10) dendrimers. An electron paramagnetic resonance (EPR) spectrometer yields information on the molecular and electronic structure of molecules. It may also be used to obtain information about the lifetimes of free radicals, short-lived species that are often essential for the initiation of tumor growth and/or a variety of chemical reactions. These studies will have an impact in a number of areas, from manufacturing to materials and biological chemistry.

在主要研究仪器（MRI）计划的支持下，阿克伦大学化学系将获得一台电子顺磁共振（EPR）光谱仪。受益于EPR的研究项目包括对顺磁材料的研究，如1）金属酶模型; 2）新型有机金属材料; 3）MRI造影剂; 4）卟啉络合物; 5）生物材料; 6）导电聚合物; 7）甲硅烷基自由基; 8）粉末涂料; 9）催化剂;和10）树枝状聚合物。 电子顺磁共振（EPR）光谱仪产生分子和分子电子结构的信息。它还可以用于获得有关自由基寿命的信息，自由基是通常对肿瘤生长和/或各种化学反应的起始至关重要的短寿命物质。这些研究将在许多领域产生影响，从制造到材料和生物化学。
