通过对三种类型十个有机簇合物在十种有机溶剂中紫外－可见光谱的测试及计算机辅助处理，得到了簇合物在一些溶剂中ＵＶ－ＶＩＳ谱ＣＴ带的ｖｍａｘ／ｃｍ－１和溶剂的极性参数（ｎ２－１）／（２ｎ２＋１）、Ｚ值之间存在着较好的线性关系，其相关系数分别达到了０．９８４～０．９９０。本文还对ＣＴ带的／ｃｍ－１和（ｎ２－１）／（２ｎ２＋１），ＥＴ（３０）进行了二元线性回归处理，得到了更好的线性关系，相关系数为０．９９８～０．９９９９。本文还研究了二元混和溶剂中组分的摩尔百分含量与λｍａｘ相关规律，首次提出了解释这种相关规律的＂选择性溶剂化＂效应，或称＂优先性溶剂化＂效应，且通过计算机拟合得出了簇含物ＣＴ带λｍａｘ与溶剂组成的摩尔百分含量之间的非线性相关关系数学式。
Vmax / cm-1 and UV-VIS spectra of cluster bands in some solvents were obtained by testing the UV-Vis spectra of ten organic clusters of three types and ten computer-aided treatments. There is a good linear relationship between the polarity parameters (n2-1) / (2n2 + 1) and the Z values of the solvents, and their correlation coefficients reach 0.984-0.990. In this paper, the binary linear regression of / cm-1 and (n2-1) / (2n2 + 1) and ET (30) in CT band is also processed, and a better linear relationship is obtained with a correlation coefficient of 0.998-0. 9999. In this paper, the relationship between the mole percentage of components in the binary mixed solvent and λmax was also studied. For the first time, the “selective solvation” effect, or the “preferential solvation” effect, which explains the related law, Computer fit obtained the nonlinear correlation between the λmax of the cluster and the mole% of the solvent composition.
