Acquisition of an Electron Spin Resonance Spectrometer

电子自旋共振（ESR）光谱允许化学家 对材料进行极其精确的高分辨率研究 含有不成对电子（顺磁性化合物）。 等 研究揭示了分子结构的信息， 任何其他技术都无法实现。 化学共享仪器计划（Chemistry Shared Instruments Program） 将帮助哥伦比亚大学化学系 找一个ESR光谱仪 化学研究领域 将通过收购得到加强的包括以下内容： 1)无机配合物探针的开发与应用 生物聚合 2)稳定自由基和双自由基的制备 3)设计分子和实验来探测电子和 电荷转移过程 4)利用磁场、磁性同位素和磁性 光化学过程的共振效应 5)自由基气相化学研究的ESR方法 反应.

Electron Spin Resonance (ESR) spectroscopy allows chemists to conduct extremely precise high resolution studies on materials containing unpaired electrons (paramagnetic compounds). Such studies reveal information on molecular structure that is unavailable by any other technique. This award from the Chemistry Shared Instrumentation Program will help the Department of Chemistry at Columbia University to acquire an ESR spectrometer. The areas of chemical research that will be enhanced by the acquisition include the following: 1) Development and application of inorganic complexes to probe biopolymers 2) Preparation of stable radicals and diradicals 3) Design of molecules and experiments to probe electron and charge transfer processes 4) Use of magnetic field, magnetic isotope and magnetic resonance effects on photochemical processes 5) ESR methods for the study of free radical gas phase chemical reactions.
