## Abstract We have presented a systematic experimental investigation of carboxyl oxygen electric‐field‐gradient (EFG) and chemical shielding (CS) tensors in crystalline amino acids. Three ^17^O‐enriched amino acids were prepared: L‐aspartic acid, L‐threonine, and L‐tyrosine. Analysis of two‐dimens
