论文部分内容阅读
The P=O bond dissociation enthalpies(BDE) were calculated using high-level ab initio methods including G3,G3B3,CBS-Q,CBS-4M,CCSD(T),and MP2.Based on the comparison of these theoretical values and experimental ones,the performances of a number of density functional theory (DFT) methods were then assessed.
