    苯并恶唑类化合物的研究——Ⅱ.紫外吸收光谱和Stokes位移的溶剂效应

    • 摘要: 测定了四种苯并恶唑类化合物在17种溶剂中的紫外吸收和荧光发射光谱,用五种方法对絮外吸收光谱和Stokes位移的溶剂效应进行了关联。结果表明:Nicol关系式能很好地描述溶剂对溶质分子的紫外吸收峰值的位移效应。利用Lippert方程还计算了这四个化合物在第一激发单线态的偶极矩。

       

      Abstract: UV absorption and fluorescence emission spectra of four benzoxazole compounds in seventeen solvents were measured. Effects of solvent on UV absorption spectra and Stokes' Shift were investigated by five different methods. The results show that Nicol Equation can well describe the effects of solvent on the Shift of UV absorption peak value of solute. In addition, the dipole moments of four compounds in the first excited singlet state were calculated by using Lippert Equation.
