Knowledge of chemical shift-structure relationships could greatly facilitate the NMR chemical shift assignment and structure refinement processes that occur during peptide/protein structure determination via NMR spectroscopy. To determine whether such correlations exist for polar side chain containi
## Abstract NMR–chemical shift structure correlations were investigated by using GIAO‐RB3LYP/6‐311++G(2d,2p) formalism. Geometries and chemical shifts (CSI values) of 103 different conformers of N′‐formyl‐L‐histidinamide were determined including both neutral and charged protonation forms. Correlat
