Abstract DFT/B3-LYP(6-31++G**) calculations are used to provide information on closed N – H ⋯ O H -bonded complexes, containing two hydrogen bonds. The studied model systems with two H-bonds are the 2-pyridone dimer, 2-pyridone–H2O and 2-pyridone–CH3OH.

Photoionization of 2-pyridone and 2-hydroxypyridine
Physical Chemistry Chemical Physics, 2010We studied the photoionization of 2-pyridone and its tautomer, 2-hydroxypyridine by means of VUV synchrotron radiation coupled to a velocity map imaging electron/ion coincidence spectrometer. The photoionization efficiency (PIE) spectrum is composed of steps.
