顺磁性

At the normal state, porphyrin molecules do not have EPR signal. However, light excitation may cause a transition of porphyrin molecules from singlet to triplet. At the same time, the change from diamagnetism to paramagnetism occurred to porphyrin molecules. In this case, the two un-paired electrons are nearby each other and cause a strong interaction, giving EPR signal with sharp peak at g =2.000. The g value increased with an increase in electron cloud density.

常态下卟啉分子没有EPR信号，在光的激发下，卟啉分子由原来的逆磁性分子变成顺磁性的激发三重态分子，这种激发三重态分子在分子轨道上具有两个未成对电子，这两个电子相距很近，彼此之间发生很强的相互作用而产生电子，它的 g 值随卟啉共轭体系平均电子云密度增大而变大。
