Purchase of a Replacement Circular Dichroism Spectrometer

这份来自化学研究仪器和设施（CRIF）项目的合同将帮助俄亥俄州立大学化学系升级圆二色（CD）光谱仪。此次收购将加强以下领域的化学研究：(a)肽去甲酰基酶：机制和抑制剂设计；(b)酶的机制和结构-功能关系；(c)用于不对称催化的水溶性树状大分子；(d) CD光谱监测金属配合物与DNA的协同结合；(e) Fe-S蛋白和裂解肽的结构-功能研究；(6)信号肽酶的结构-功能研究长期以来，光学活性的测量在有机化学和生物化学的发展中起着重要的作用。旋光色散（ORD）或圆二色性（CD）的研究提供了关于单个分子或离子的电子态或结构的重要信息。这些技术用于研究分子的绝对构型、反应机理和动力学、不对称或立体定向合成、溶解物质的热力学性质以及许多其他立体化学问题。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will assist the Department of Chemistry at Ohio State University to upgrade a Circular Dichroism (CD) spectrometer. The acquisition will enhance chemical research in the following areas: (a) peptide deformylase: mechanism and inhibitor design; (b) enzyme mechanisms and structure-function relationship; (c) water-soluble dendrimers for asymmetric catalysis; (d) cooperative binding of metal complexes to DNA monitored by CD spectroscopy; (e) structure-function studies of Fe-S proteins and lytic peptides; (6) structure-function studies on signal peptidase 1. Measurements of optical activity have long played an essential role in the development of organic chemistry and biochemistry. The study of optical rotatory dispersion (ORD) or circular dichroism (CD) provides important information about the electronic states or structures of individual molecules or ions. These techniques are used when studying absolute configurations of molecules, reaction mechanisms and kinetics, asymmetric or stereospecific synthesis, thermodynamic properties of dissolved species, and many other stereochemical problems.
