We have presented a solid-state (17)O NMR study of [(13)C, (17)O]-l-alanine. Using the experimental results for the (13)C-(17)O dipolar vector and Euler angles, the absolute orientations of (17)O chemical shielding (CS) and electric-field-gradient (EFG) tensors with respect to the molecular frame can be determined for l-alanine. The present results suggest that the intermediate EFG tensor components, V(YY), lie in the carboxylate plane and parallel to the C-O bond directions, while the least shielded components, delta(11), and the intermediate CS tensor components, delta(22), roughly lie in the molecular plane and the direction of delta(22) components are approximately 38 degrees and 25 degrees off the C-O bonds for O1 and O2, respectively. These results are in reasonable agreement with those of our quantum chemical calculations reported previously.
