My book states that ortho nitrophenol (I)undergoes intramolecular H-Bonding while para nitrophenol (II)undergoes intermolecular bonding.

My question is does (I) show any intermolecular H-bonding as well?If yes, is there a parameter by which we can quantitatively determine the (%) of intermolecular and intramolecular H-bonding in each compund?
