摘要: 本文报道了人工合成铁叶啉-Fe(OEP)Cl,Fe(NO2)(OEP)Cl和Fe(NO2)2(OEP)Cl,在77K、300K和室温下外加5KOe磁场时测得的穆斯堡尔谱。用电子自旋-自旋弛豫机制解释了谱线的变化,并讨论在叶淋环中位取代不同数目的(NO2)基所引起同质异能移位的微小变化。

Abstract: The Mossbauer Spectra of the synthetic iron porphyrins Fe (OEP) Cl, Fe (NO2) (OEP)Cl, and Fe(NO2)2(OEP)Cl were measured at 77k, 300k and in anexternal megnetic field of 5KOe at room temperature. The Changes of the spectral shape was explained by electron Spin-Spin relaxation. The small difference of the isomer shift caused by the different number of NO2-groups substituted for the meso-positions in the pyrrole ring was discussed.
