众多的有机磷化合物(例如磷酸酯或硫代磷酸酯等)均可用作毒剂或农药,因此有关P=O及P=S的结构与红外谱带相互联系的研究,不论从理论上或从实践上讲都有其重要的意义。前文我们曾经对有机磷化合物与取代基电负性和的关系作了报导,本文再就v_(p=s)与取代基电负性和的关系作一探讨。 关于硫磷键的红外光谱数据已积累了很多,指出:P=S频率在540—750cm~(-1)
Numerous organophosphorus compounds (such as phosphates or phosphorothioates, etc.) can be used as toxicants or pesticides. Therefore, the study on the relationship between the structure of P = O and P = S and the infrared bands, whether theoretically or In practice, it has its important significance. We have previously reported on the relationship between the organophosphorus compounds and the electronegativity of the substituents reported in this paper and v_ (p = s) and the relationship between the electronegativity of substituents for a discussion. Infrared spectroscopy data on the sulfur-phosphorus bond has accumulated a lot, pointed out: P = S frequency at 540-750cm ~ (-1)
