Molecular orbital study of some aromatic N-oxide systems was written by Chadha, Rita. And the article was included in Indian Journal of Chemistry, Section A: Inorganic, Physical, Theoretical & Analytical in 1986.Recommanded Product: 3718-65-8 This article mentions the following:
The effect of substituents on the π-electronic charge distributions in a set of monosubstituted pyridine N-oxides has been analyzed by means of PPP calculations The electronic charge distribution in the ring has been used to predict the electrophilic and nucleophilic reactivities of these systems. The UV spectra of some N-oxide systems have also been calculated and compared with the exptl. ones. The π-electronic charges, bond orders and energies of MOs have been correlated with exptl. quantities such as the proton magnetic resonance chem. shifts, IR stretching frequencies and polarog. half-wave reduction potentials. The unrestricted-Hartree-Fock method of Amos and Snyder (1964) has been used to calculate the spin d. distributions in some N-oxide radical anions. Empirical relation between the spin densities and exptl. ESR hyperfine splitting constants have been derived. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Recommanded Product: 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Recommanded Product: 3718-65-8
