The concentration dependent behavior of the proton resonance spectra of salicylaldehyde in several solution systems were measured. The behavior of the OH resonance line for the solution systems showed the evidence of the existence of considerably strong intramolecular hydrogen bond in the molecule. The behavior of the ring proton spectrum on dilution suggested the occurrence of the charge migration in the ring affected by the change in the hydrogen bonding situation.
