Calculation of electronic spectra of azabenzenes and azanaphthalenes by the Pariser-Parr-Pople method was written by Favini, Giorgio;Vandoni, Ida;Simonetta, Massimo. And the article was included in Theoretica Chimica Acta in 1965.Recommanded Product: 322-46-3 This article mentions the following:
The semiempirical treatments of Pariser and Parr and of Pople were used to calculate transition energies and intensities of the 锜?锜?sup>* bands in the electronic spectra of 31 azines (azabenzenes and azanaphthalenes). A comparison with exptl. data and a discussion of the wave functions for the ground and excited states are presented. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Recommanded Product: 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging. A number of pyrazine-based derivatives were used as dyes or fluorescent probes.Recommanded Product: 322-46-3
