Both 13C-and 15N-REDOR experiments were performed to determine the '3C-'5N interatomic distance in [ I-"C]N-acetyl-Pro-[ '5N]GIy-Phe crystal and to evaluate the inter-or intra-molecular dipolar contributions leading to its errors. The interatomic distance was determined to be 3.43 8, after removing

## Abstract It is demonstrated that in a case where neither the proton nor the natural‐abundance ^13^C‐satellite spectra of a partially oriented molecule carry enough structural information, one can determine the entire molecular geometry by the combined use of several liquid crystals as solvents.
