The 13 C NMR spectra of nine isomeric E ‐hydroxyazastilbenes ( E ‐hydroxystyrylpyridines) have been fully assigned. The Ai and AiK empirical parameters of o ‐( m or p ‐)hydroxystyryl and 2‐(3‐ or 4‐)vinylpyridyl groups for the prediction, of chemical shifts of substituted styrylpyridines were calculated.
