The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《S.C.F.-M.O. calculations of heteroatomic systems with the variable-β approximation. II. Electronic spectra of hydroxy aza-aromatic molecules》.

Through the article, more information about this compound (cas:7651-82-3) is conveyed.
cf. CA 64, 7527c. The spectra of the pyridinols, quinolinols, isoquinolinols, quinolones, and isoquinolones have been calculated by a variable-β procedure within the Pariser-Parr-Pople S.C.F. approximation The relative positions and intensities of the lower excited states in hydroxy aza-aromatics vary considerably with substituent position, and the calculations agree well with experiment The vector addition of spectroscopic moments leads to transition moments that differ little from those obtained directly from the S.C.F.-M.O. calculations 17 references.
