本文报道了反式-二氯、二水、二羟基和二硫氰基二(乙二胺)铬(IIl)络合物的低温玻璃溶液的电子顺磁共振(EPR)谱。用一种适用于其它零场分裂比Hv大的过渡金属离子系统的方法，从光谱中确定了自旋-哈密顿参数。结果表明，实验测定的反式铬(Ea“+)络合物的自旋哈密顿参数E的绝对值与相应的CrA83±络合物的可见吸收光谱中A配体的配位场强度成正比。
Electron paramagnetic resonance(epr) spectra are reported for low-temperature glassy solutions of the trans-dichloro-,-diaquo-,-dihydroxo-, and-dithlocyanatobis (etliylenediamme) chromium (IIl) complexes. Spin-Hamiltonian parameters are determined from the spectra by a method applicable to other transition metal ion systems with zero-field splittings large in comparison to hv. It is shown that the absolute magnitude of the experimentally determinedspin-Hamiltonian parameter E for these trans-Cr (ea”+ complexes is proportional to the ligand field strength of the A ligands as deduced from the visible absorption spectra of the corresponding CrA83±complexes.
