In the solid state the dimeric form is not present; the 2-pyridones form a helical structure over hydrogen bonds. Some substituted 2-pyridones form the dimer in solid state, for example the 5-methyl-3-carbonitrile-2-pyridone. The determination of all these structures was done by X-ray crystallography. In the solid state the hydrogen is located ...
Whereas 2-pyridone (α) and 4-pyridone (γ) predominantly adopt the oxo form, the 3-pyridone (β) cannot, and instead adopts an equilibrium of the zwitterion form, pyridin-1-ium-3-olate, and the enol form, 3-hydroxypyridine (the canonical form). The 3-pyridone is not mesoionic. This property of 3-hydroxypyridine is leveraged in biology in ...

It's 2-hydroxypyridine in gas phase, and the more polar the solvent, the more stable the 2-pyridone. The explanation for this is stabilization of charge separation in high dielectric environments. 2-pyridone has greater charge separation, as can be seen by considering its mesionic aromatic resonance contributor.
