在用电予顺磁共振方法研究单晶体时,对于样品的不同温度,经常要求得到电予顺磁共振谱线参数的角度关系,及其不高的定向绝对精度(约为1度)。例如在晶体中确定顺磁中心的形式、建立其自旋哈密顿算符等情况下,提出了这样的任务。但是,一般来说用于样品 In the study of single crystal by the method of paramagnetic resonance, it is often required to obtain the angle relationship of the paramagnetic resonance line parameters and its low absolute orientation accuracy (about 1 degree) for different sample temperatures. For example, in the crystal to determine the form of paramagnetic center, the establishment of its spin Hamiltonian and so on, the proposed task. However, it is generally used for samples
