Experimental and theoretical studies on the magnetic circular dichroism of azanaphthalenes. Use of the CNDO/S-CI approximation was written by Kaito, Akira;Hatano, Masahiro. And the article was included in Journal of the American Chemical Society in 1978.Recommanded Product: 322-46-3 This article mentions the following:
The magnetic CD spectra of quinoline, isoquinoline, quinoxaline, phthalazine, quinazoline, cinnoline and pyrido[2,3-b]pyrazine were measured in the waveno. region 20,000-50,000 cm-1. The transition energies, oscillator strengths and Faraday B terms calculated within the framework of the CNDO/S-Cl approximation agree with the exptl. results. The signs of the Faraday B terms of 2 lowest π* ← π transitions change according to whether the aza substitution occurs at the α or β position. The origins for the Faraday B terms of the lowest allowed π* ← n transition and the 2 lowest π* ← π transitions were also investigated. 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 has the elements of symmetry for the point group D2h. It has three mutually perpendicular two-fold axes. It also has three mutually perpendicular planes of symmetry. As a result, pyrazine also has a centre of symmetry. Pyrazine-based skeletons were incorporated into agents targeting a range of ailments. Many derivatives were synthesized and evaluated as potential cancer treatments.Recommanded Product: 322-46-3
