摘要 采用量子化学从头算的HF,MP2,QCISD方法和密度泛函中的B3LYP方法,在不同基组6 311G(d) , 6 311G(2df) , 6 311G(3df) , 6 311++G(3df) 水平上对草酰碘中性分子(ICO)2 作了构像分析.结果表明,在不同基组水平上,由MP2,QCISD,B3LYP方法均能得到草酰碘分子的交叉式构型和平面反式构型,与实验所得草酰卤化物的构型完全相符. The molecular structure and conformationals natural of oxalyl iodide (ICO)_2 are investigated by the ab initio and DFT methods with 6-311G(d), 6-311G(2df), 6-311G(3df), 6-311++G(3df) basis set. The result shows that MP2, QCISD, B3LYP can gain the gauche and anti conformers of oxalyl iodide, which is in good agreement with configuration of oxalyl halides in experiment.
