Deconvolution of Raman spectroscopic signals for electrostatic, H-bonding, and inner-sphere interactions between ions and dimethyl phosphate in solution

Raman spectroscopic signals for inner-sphere, H-bonding, and electrostatic interactions are sufficient to account for the total ion-induced change in the Raman signal for non-bridging phosphate oxygen (νsPO2−) and are consistent with relative levels of coordination predicted from absolute electronegativity and absolute hardness of alkali and alkaline earth metals.
