WebThe vibration frequencies of some phosphate esters have been measured in the 900–1400 cm −1 region. Only some show a correlation between the P=O vibration frequencies and the Taft polar constants. It is concluded that the polar effect of the substituents is the main factor affecting the P=O vibration frequencies, but not the only one. WebThey are strongest on directly bound atoms, but continue to have an effect on atoms adjacent to those they are directly bonded to, and beyond. Thus in the case of an anhydride, the bond characteristics of each carbonyl bond are somewhat impacted by the stretching of the other carbonyl bond.
