摘要 使用量子化学 ab initio计算方法(RHF)、密度泛函法(B3LYP)和 MP2 法,在 6 311++G(d,p)和AUG CC PVTZ基组水平下,对氟代磷杂硫烯酮、氯代磷杂硫烯酮及其相关分子进行了全优化几何构型的量子化学计算.计算结果表明,氟代和氯代磷杂硫烯酮为累积双烯结构,磷杂硫烯酮的异构体含 C P 三键,所有分子都具有弯曲几何构型. Fluophosphathioketen、chlorophosphathioketene and related molecules were calculated by several methods of quantum chemistry in Gaussiang-98 programme.Optimized geometries were obtained at ab initio(RHF)、DFT(B3LYP)and MP_2 levels using 6-311++G(d,p) and AUG-CC-PVTZ basis sets.The results of calculation show that fluophosphathioketene and chlorophasphatioketene presents cumulative double bonds, isomer presents C(P)triple bonds, all of molecules have a trans-bent geometries.
