Purchase of a Cryostat

化学研究仪器计划的这一奖项将帮助科罗拉多大学博尔德分校的化学系获得低温Heliplex系统，该系统将与EPR-Endor光谱仪一起使用，以便在低温下进行磁性测量。该装置将用于下列化学领域的研究：1)活性中间体，2)含有苯二酚的过渡金属络合物，3)分子体系中的合作现象。低温学涉及极低温度的产生和维持，以及在这些温度下的现象研究。与该合同一起购买的低温恒温器将允许在接近绝对零度的温度下进行测量。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at the University of Colorado at Boulder acquire a Cryogenic Heliplex System, which will be used with an EPR-ENDOR spectrometer to enable magnetic measurements at low temperatures. The equipment will be used in research investigations in the following areas of chemistry: 1) reactive intermediates, 2) transition metal complexes containing quinone liqands, and 3) cooperative phenomena in molecular systems. Cryogenics relates to production and maintenance of very low temperature, and the study of phenomena at these temperatures. The cryostat which will be purchased with this award willallow measurements to be made at temperatures near absolute zero.
