Computed Properties of C9H7NO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 8-Hydroxyquinoline 1-oxide, is researched, Molecular C9H7NO2, CAS is 1127-45-3, about Solvent effect on the intramolecular hydrogen bond in 8-quinolinol N-oxide. Author is Dziembowska, T.; Malarski, Z.; Szczodrowska, B..
Solvent effect on intramol. hydrogen bond in 8-quinolinol N-oxide has been studied by IR, UV, 1H NMR and 13C NMR spectroscopy, dipole moment measurements and quantum-mech. calculations The solute-solvent interactions are of local character and they vary considerably over the range of solvent under study. The results suggest that formation complexes with solvent mols. weaken the intramol. hydrogen bond in 8-quinolinol N-oxide.
