[求助] 电子顺磁共振（electron paramagnanetic resonance，EPR）能测试电导率？

EPR study of polyaniline highly doped by p-toluenesulfonic acid 论文中：

Magnetic, relaxation and electronic dynamic parameters of paramagnetic centers in crystalline domains of polyaniline highly doped by
p-toluenesulfonic acid (PANI-PTSA) as well as PANI-PTSA dispersed in poly(methyl methacrylate) (PANI-PTSA/PMMA) were studied by
the 3-cm (9.7 GHz) and 2-mm (140 GHz) wavebands EPR. At both wavebands these polymers demonstrate the Lorentzian single line with
the Dysonian contribution indicating intrinsic conductivity of metal-like domains ca. 1500-4000 S/cm at room temperature.

居然有电导率测试？是计算的推测结果？还是直接测试如同4探针法测试结果？
