描述了一种装置，其设计用于测量EPR中的线性电场效应，例如在生物物理研究中经常遇到的非晶样品。该装置是基于电子自旋回波法。它能够测量相位记忆时间为<$1 μsec的样品的g偏移<$10 −9 cm/V。本文对电子自旋回波装置作了简要的介绍，特别注意了为测量线性电场效应而专门研制的系统的某些部分。电场的均匀性和测量的脉冲定时参数的影响进行了详细的研究。
An apparatus is described which is designed to measure the linear electric field effect in EPR for amorphous samples such as those which are often encountered in biophysical studies. The apparatus is based on the electron spin echo method. It is capable of measuring g shifts ≃ 10−9 cm/V for samples with phase memory times ≃ 1 μsec. A brief general description of the electron spin echo apparatus is given, special attention being paid to those parts of the system developed specifically for the purpose of measuring the linear electric field effect. The influence of electric field homogeneity and of the pulse timing parameters on the measurements has been investigated in detail.
