摘要
用ＵＶ光谱和平衡透析数据证实Ｎｉ（Ⅱ）－ＨＳＡ和Ｎｉ（Ⅱ）－ＢＳＡ的１：１体系内均有２个强偶合的金属中心，它们的ＬＭＣＴ谱带显示一种新型的减色效应，这一效应符合生色基跃迁偶极矩间的偶极－偶极相互作用机理。
The data of the ultra-violet spectra and the equilibrium dialysis prove that both 1:1 systems of Ni(Ⅱ)-HSA and Ni(Ⅱ)-BSA have two strong coupling metal-centers with their LMCT bands showing a novel hypochromic effect.This effect is in consistent with the mechanism of dipole-dipole interaction between the electric dipole transition moments of chromophores.
