Abstract
The vibrational spectra of 3-hydroxypyridine 1-oxide and its derivatives were investigated.
On the basis of the assignments of the bands that characterize the OH, N+→C+, and ring C-C bonds, it was established that these compounds exist in the crystalline state as associated zwitterions. It was shown that such associates have a more delocalized π-electron system than the monomers.
