The infrared spectra of some sixteen nitrates were observed in tributyl phosphate solvent. The splitting of the nu /sub 3/ band of the nitrate ion is followed in particular. The findings are shown to be consistent with the concept that in general in these solutions a co-ordinate bond is formed between the anion and the metallic cation. The exceptions are pointed out, and it is established that a splitting of about 100 cm/sup -1/ serves as a defensible division between essentially electrostatic splitting (lower) and splitting due to co-ordinate binding (higher). The correlation between the tributyl phosphate spectra and the vibrational spectra in the solid crystals is pointed out, and with it the apparent fact that even in the conventionally ionic crystals the interaction with the cation is sufficient to modify the vibrational pattern to that of the co- ordinately bound ligand.
