Abstract
The IR spectral data of 3-hydroxypyridine and 8-hydroxyquinoline in the condensed state show that the two compounds are present in ionic form, while in the gaseous-phase state they are present in a neutral form. In 8-hydroxyquinoline in the gaseous-phase, a weaker intramolecular hydrogen bond is retained than in the CCl4 solution.
