/sup 31/P nuclear magnetic resonance chemical shielding tensors have been measured from single crystals of L-O-serine phosphate and 3'-cytidine monophosphate. The principal elements of the shielding tensors are -48, -2, and 51 ppM for serine phosphate and -68, -13, and 64 ppM for 3'-cytidine monophosphate, relative to 85% H/sub 3/PO/sub 4/. In both cases four orientations of the shielding tensor on the molecule are possible; in both instances one orientation correlates well with the P--O bond directions. This orientation of the shielding tensor places the most downfield component of the tensor in the plane containing the two longest P--O bonds and the most upfield component of the shielding tensor in the plane containing the two shortest P--O bonds. A similar orientation was reported for the /sup 31/P shielding tensor of phosphorylethanolamine and a comparison is made between the three molecules.
