Solid-state NMR study of Schiff base derivatives of 2-hydroxynaphthaldehyde. Deuterium isotope effects on 15N chemical shifts in the solid state.
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, deltaN(D), in the solid state. DeltaN(D) in the solid state provided evidenced for the presence of a dynamic proton transfer equilibrium in the solid state at the room temperature.
