测定了通式为双(1，2-环己二酮二肟)铁(II)XY和酞菁铁(II)(Z)2的化合物的穆斯堡尔谱，其中X，Y，Z代表轴位上的配体。光谱由四极分裂偶对组成，由此得到两个参数：异构体移位δ和四极分裂Δ方程。在这两系列络合物中，这些参数似乎彼此线性相关。这种关系只有当配体可以被认为是纯π受体或纯π供体时才存在。
Mossbauer spectra of compounds having the general formulae bis(1, 2-cyclohexanedione dioxime) iron (II) XY and phthalocyanineiron(II)(Z)2, where X, Y, Z represent ligands at the axial positions, have been measured at 77°K and in some cases at room temperature. The spectra consist of quadrupole-split doublets, from which two parameters have been obtained : the isomer shift δ and the quadrupole splitting, ΔEQ. These parameters appear to be linearly related to each other within both series of complexes. It is argued that such a relationship exists only when the ligands can be considered to be either pure π-acceptors or pure π-donors.
