How does the intramolecular proton transfer change on the partial change of the saturation characteristics in 8-hydroxyquinoline? A detailed computational study.

CONTEXT: Intramolecular proton transfer (IPT) has been investigated in 8-hydroxyquinoline (8-HQ) and one of its derivatives, 5,6-dihydroquinolin-8-ol (8-DQ). Computations identify the global minima as the enol (E) in S0 and the proton transferred ket…
