twenty one solvents in the range from 300 to 600 nm. The effect of specific and non-specific solvent–solute interactions on the absorption maxima shifts were evaluated by using the Catalán solvent parameter set. Furthermore, the experimental findings were interpreted with the aid of ab initio MP2 and time-dependent density functional (TD-DFT) methods. It was found that different substituents significantly
在300至600 nm范围内的二十一种溶剂中记录了十二种5-芳基-2,4-噻唑烷二酮的吸收光谱。通过使用Catalán溶剂参数集来评估特定和非特定溶剂-溶质相互作用对最大吸收位移的影响。此外,借助从头开始的MP2和时间依赖性密度泛函(TD-DFT)方法解释了实验结果。发现不同的取代基显着改变分子中的共轭程度,并进一步影响其分子内电荷转移特性。
