Time domain ESR is an indispensable technique for the study of paramagnetic relaxation mechanism and the dynamic processes, it is also an important way for enhencement of sensitivity and resolution of spectra. But the frequency domain is still used widely in ESR technique, and the time domain ESR (including FT) is not well developed as fast as FT-NMR now. It is discussed in this paper, and we conclude that time domain ESR would be developed quickly by the application of a slightly different way from PFT-NMR...

It is discussed in this paper, and we conclude that time domain ESR would be developed quickly by the application of a slightly different way from PFT-NMR under the improvement of microwave technology, fast pulse circuits and computer techniques.

时间域电子自旋共振(ESR)是研究顺磁弛豫机理和动力学过程不可缺少的方法,也是提高检测信号的灵敏度和分辨率的重要途径之一。然而,目前在ESR技术中较常用的还是频率域,而时间域ESR(包括付里叶变换法)却远远不如脉冲付里叶变换核磁共振(PFT-NMR)那样迅速的发展。本文对此进行了讨论,认为:如采用与PFT-NMR稍为不同的方法,并在微波技术、快速脉冲电路和电子计算技术等不断改善的基础上,时间域ESR势将成为今后发展的大方向。 近年来,在时间域ESR技术方面,最引人重视的是:饱和恢复法和电子自旋回波(ESE)法。本文着重对这两种方法的基本原理、实验方法、应用场合及其优越性和局限性进行了评述。例如,用付里叶变换法(包括二维付里叶变换)把电子自旋回波调制的包络自时间域变换成频率域,从而获得高分辨率的频谱,则可分析出取向或无规取向样品的微弱超精细结构。又如,ENDOR(电子-核双共振)自旋回波与通常的ENDOR相比,前者具有较高的灵敏度以及可检测较低的ENDOR频率等独特之处。 此外,文中对瞬态顺磁中间产物的时间分辨ESR和三重态分子在零场中的ESR也分别进行了简短的评介。最后,对时间域ESR发展的远景作...
