It is demonstrated on a polycrystalline powder sample of Cd3(PO4)2, given a known single-crystal X-ray structure, that two-dimensional 31P double-quantum single-quantum MAS correlation experiments allow unique assignment of multiple 31P resonances to specific P sites in the structure of such inorganic orthophosphates. The eigenvalues of the 31P and 113Cd shielding tensors of Cd3(PO4)2 are reported, the determination of which requires usage of a 2D MAS spinning sideband separation experiment.
