In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called π-Electronic structure and electronic spectra of methylated 3,5-dicyanopyridines, published in 1977, which mentions a compound: 1195-58-0, mainly applied to methyldicyanopyridine UV MO; cyanopyridine UV MO; pyridine cyano UV MO, Formula: C7H3N3.
Quantum-chem. interpretation is given for the UV spectra of mono-, di-, and trimethylated title compounds using the limited-configuration-interaction method on the bases of Hueckel MO and SCF wave functions. Results of both procedures agree well with exptl. The modifications agree also in qualities of individual transitions and weights of configurations. The influence of Me-group on 3,5-dicyanopyridine skeleton was followed by the electron d. change.
I hope my short article helps more people learn about this compound(Pyridine-3,5-dicarbonitrile)Formula: C7H3N3. Apart from the compound(1195-58-0), you can read my other articles to know other related compounds.
