摘要:

电子自旋共振(ESR)波谱技术自1944年发现以来, 迄今已在化学、物理学、地矿学、生物学特别是生命科学的许多领域得到广泛应用, 由初期主要是对长寿命和稳定的顺磁粒子的研究, 逐步发展到对短寿命中间体, 反应过程机理和动力学的研究. 在检测技术方面, 日益广泛 地采用自旋标记, 自旋捕捉, 时间分辨ESR, 电子核双共振, 化学诱导动态电子极化(CIDE P )和自旋回波等技术. 我国从20世纪50年代末开始将ESR技术用于某些研究领域, 80年代以后有了很快的发展. 以下仅就我国几十年来ESR研究领域的几个主要方面予以简单回顾. 有关文献引用只限于国内外核心刊物正式发表的论文和报道.

1. Studies on ESR instruments, detection methods and applications of  new techniques;
2. Studies on the fundamental theory concerning ESR;
Theoretical exploration to the mathematical; model, calculating and descri bi ng methods for quantitative interrelations between spin spectrum parameters, opt ical spectrum properties, crystal field parameters, magnetic behavior and bond p arameters of paramegnetic species by using the theories and methods of quantum m echanics, group theory and crystal field-ligand field theories. The substance includes: spin-orbital interaction and spin-spin interaction mechanism research ; Calculations for g-tensor, superfine coupling constants, optical spectrum levels and zero-field splitting parameters; Correlation of crystal field param eters with zero-field splitting parameters and g-tensor etc.. At the same  time, chemically induced dynamic electron polarization(CIDEP) as well as its mec hanisms were studied.
