具有轴对称g, A张量的粉末ESR线型表达式
摘要:
本文推导了s=1/2, g、A均为轴对称张量并具有相同主轴坐标系的粉末ESR线型表达式, 利用这种表达式计算的曲线能与实验曲线很好地吻合。

EXPRESSIONS FOR ESR LINESHAPE OF POWDER SAMPLES WITH AXIALLY ANISOTROPIC g AND A TENSORS
Abstract:
Any axilally symmetric ESR powder pattern can be divided into several component curves.Each of them has only one step and one divergence peak. According to this idea, approximate expressions for the powder pattern based on a delta line shape of an individual crystallite are presented and ones based on a Lorentzian line shape are also derived.The calculated spectra for powder K_3CrO_3 and CuTAPP are in od agreemant with experimental ones.
