用INDO系列方法对C28H3Cl, C28H2Cl2, C28HCl3, CH3Cl, CH2Cl2, CHCl3进行了几何构型优化, C28H3Cl, C28HCl3, CH3Cl, CH3Cl为C3v对称性,C28H2Cl2, CH2Cl2为C2v对称性, 这六个分子的基态都是稳定闭壳层分子, 以此构型为基础计算了上述分子的电子光谱, C28H4-nCln(n=1~3)的电子光谱属于理论预测性质。

The geometry optimization of C28H3Cl, C28H2Cl2, C28HCl3, CH3Cl, CH2Cl2, CHCl3 have been performed by INDO series methods, C28H3Cl, C28HCl3, CH3Cl, CHCl3 are C3v symmetry and C28H2Cl2, CH2Cl2 are C2v symmetry. The ground states of above six molecules are stable closed- shell molecules. On the base of these geometries, the electronic spectra of above molecules have been calculated. The electronic spectra of C28H4-nCln(n=1~3) are theoretical predictions.
