描述了一些铁族复杂氰化物的顺磁共振实验结果。找到了自旋哈密顿量的形式并测量了参数值。用同晶反磁性盐稀释的氰化铬钾和钒氰化钾（构型 3d 3）具有有效自旋 3/2，并具有菱形对称的电子分裂。 g 值接近各向同性，为 1.992，超精细结构也是各向同性。用同晶抗磁性盐稀释的铁氰化钾和锰氰化钾（构型 3d 5）具有有效自旋 1/2，各向异性 g 值在 0.6 至 2.6 之间。氰化锰还表现出各向异性超精细结构。未稀释的铬氰化钾和铁氰化钾的行为表明相邻顺磁配合物之间存在明显的交换相互作用。
The results are described of paramagnetic resonance experiments on some complex cyanides of the iron group. The form of the spin Hamiltonian is found and the values of the parameters are measured. Potassium chromi-cyanide and potassium vanadocyanide (configuration 3d 3), diluted with the isomorphous diamagnetic salts, have effective spin 3/2 with an electronic splitting of rhombic symmetry. The g-value is closely isotropic at 1.992, and the hyperfine structure is also isotropic. Potassium ferricyanide and potassium manganicyanide (configuration 3d 5), diluted with the isomorphous diamagnetic salt, have effective spin ½ with anisotropic g-values between 0.6 and 2.6. The manganicyanide also exhibits an anisotropic hyperfine structure. The behaviour of undiluted potassium chromicyanide and potassium ferricyanide suggests that there is appreciable exchange interaction between neighbouring paramagnetic complexes.
