ESR成像(Ⅰ)——TEMPOL水溶液样品的X波段一维成像

ESR Imaging(Ⅰ)--The One Dimensional X B and Imaging of TEMPOL Aqueous Solutions

用磁共振方法实现自旋分布成像是Lauterbur和1973年首先提出来的[1],经过十几年时间,核磁成像已经在医学临床上得到广泛的应用。从原理上看,将NMR成像移植到ESR成像似乎是顺理成章的事,但由于ESR在实验技术上和NMR之间存在着很大差别。

One dimensional ESR imaging has been achieved using anti-Helmholtz gradient coil on Bruker ER 200D X-b and ESR spectrometer.Examples are presented using TEMPOL aqueous solution.Finally,a preliminary two-dimensinal imaging is also included.
