Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 14248-66-9, is researched, Molecular C7H8N2O3, about Absorption and phosphorescence spectra of 4-nitropyridine N-oxides and 4- and 3-nitroquinoline N-oxides, the main research direction is nitropyridine oxide UV phosphorescence; oscillator strength nitropyridine oxide; MO nitropyridine oxide UV; pyridine oxide UV phosphorescence; nitroquinoline oxide UV phosphorescence; quinoline oxide UV phosphorescence.COA of Formula: C7H8N2O3.
SCF-MO-CI calculations were used to facilitate interpretation of the absorption, phosphorescence, and phosphorescence excitation spectra of 4-nitropyridine N-oxide (I), its 3-methyl and 3,5-dimethyl derivatives, and 3- and 4-nitroquinoline N-oxide. For I, the phosphorescence lifetime, the degree of polarization of the phosphorescence and excitation spectra, and the single-triplet energy gap were studied. The main feature of the absorption at long wavelength was intramol. charge-transfer from the O of the NO group to the NO2 group. The nature of the lowest triplet state was discussed, this state resulting from a π-π* transition and being 3A1 for I. The phosphorescence spectra exhibited a blue shift on changing the solvent from Et2O to Me2CHOH.
This literature about this compound(14248-66-9)COA of Formula: C7H8N2O3has given us a lot of inspiration, and I hope that the research on this compound(3,5-Dimethyl-4-nitropyridine 1-oxide) can be further advanced. Maybe we can get more compounds in a similar way.
