Abstract

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 PO₄^3- groups at the P2 and P4 sites have been transformed to HPO₄^2- in our octacalcium phosphate sample.
