Measured frequencies from pure nitrate liquids have been used to calculate the force constants for the nitrate ion and the M+-NO3- systems (M+ = Li+, Na+, K+, Rb+, and Cs+) by a matrix successive-approximation method based on perturbation theory in dependent coordinates. The valency force constants Kq for the N-O bonds are increased by comparison with free NO3-. The N-O bond strengthening is not adequately explained by cation-anion interaction because there is electron-density transfer mainly by the p mechanism within the NO3-. Correction for the vibrational parameters of the interacting particles confirms the previously demonstrated acid-base mechanism for the cation-anion interaction in liquids containing nitrate. |
