摘要
本文报导三种苯基磷卤化合物 C_6H_5P(O)F_2 1,C_6H_5P(O)HF 2和 O-ClC_6H_4P(O)Cl_2 3子25℃在稀苯溶液中的电偶极矩测量值,并以四面体模型利用键加和法解析出了该类分子的P=O 键偶极矩的取向与数值.
The electric dipole moments of the three phenyphosphorus halogen compounds C_6H_5P(O)F_2, C_6H_5P(O)HF and O—ClC_6H_4—P(O)Cl_2 were determined in dilute benzene solution at 25℃.The phosphoryl bond moment μp=o in these compounds were estimated by using bond—additivity based on the tetrahedral model.
