本文研究了正辛烷（C8）和正癸烷（C10）单晶中铜卟啉亚稳态态在2·3 ~ 35 K范围内，有和无磁场db时的磷光光谱。在35 K时观察到的轨道组分之间的晶体场分裂为δ = 30.3±0.3 (C8), 13.8±0.2 cm-1（C10）。从塞曼位移中，我们得到了有效轨道角动量Λ ‘ = 0.8±0.02 (C10)，自旋-轨道耦合参数|Z ’ | = 1.0±1.0 cm-1(C10)，自旋-自旋偶极相互作用参数sd = - 1.0±0.2 cm-1（C8, C10）和|E| = 0.31±0.03 cm-1(C8, C10)，以及g-因子∥= 2.14±0.04 （C8, C10）和g⊥= 2.00±0.03 （C8, C10）。
The phosphorescence spectrum of the metastable4Eustate of copper porphin in single crystals ofn-octane (C8) andn-decane (C10) has been studied between 2·3 and 35 K, with and without a magnetic fieldB. The crystal field splitting between the orbital components observed at 35 K is δ = 30·3 ± 0·3 (C8), 13·8 ± 0·2 cm-1(C10). From the Zeeman shifts we derive the effective orbital angular momentum Λ′ = 0·8 ± 0·2 (C10), the spin-orbit coupling parameter |Z′| = 1·5 ± 1·0 cm-1(C10), the spin-spin dipolar interaction parametersD= -0·1 ± 0·2 cm-1(C8, C10) and |E| = 0·31 ± 0·03 cm-1(C8, C10), and theg-factorsg∥= 2·14 ± 0·04 (C8, C10) andg⊥= 2·00 ± 0·03 (C8, C10).
