Schiff base derivatives of 2‐hydroxynaphthylaldehyde were studied by means of 13C and 15N cross‐polarization magic angle spinning NMR spectroscopy and deuterium isotope effects on 15N chemical shifts, ΔN(D), in the solid state. ΔN(D) in the solid state provided evidenced for the presence of a dynamic proton transfer equilibrium in the solid state at the room temperature. Copyright © 2005 John Wiley
