We have assigned the 31P high-resolution spectrum of octacalcium phosphate by 31P double quantum and HETCOR spectroscopy. The 31P peaks at -0.2, 2.0, 3.3 and 3.7ppm are assigned to P5/P6, P3, P2/P4 and P1, respectively. Our data reveal that substantial amount of the PO43- groups at the P2 and P4 sites have been transformed to HPO42- in our octacalcium phosphate sample.
