Is there intramolecular hydrogen bonding in salicylaldehyde? Is there intramolecular hydrogen bonding between the hydroxyl and carbonyl groups?



I think personally is that it does but what is concerning me is that I have got no adequate answer or response to my suggestion, so if anyone could help on this one, that would be great.
It can indeed hydrogen bond, this can (to a certain extent) be observed by NMR. Due to the internal hydrogen bonding, the phenolic proton is surprisingly consistent, and shows no dependence on concentration.
