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
While (15)N solid-state NMR has proven to be very advantageous for the development of structural biological methods, (13)C spectroscopy has increased sensitivity and spectral dispersion. However, large natural abundance signals and homonuclear dipolar interactions pose significant problems. Here we
## Abstract According to the ^1^H, ^13^C and ^15^N NMR spectroscopic data and DFT calculations, the __E__‐isomer of 1‐vinylpyrrole‐2‐carbaldehyde adopts preferable conformation with the __anti__‐orientation of the vinyl group relative to the carbaldehyde oxime group and with the __syn__‐arrangement
