The out-of-plane vibrations of aza-aromatic molecules was written by Chappell, P. J.;Ross, I. G.. And the article was included in Journal of Molecular Spectroscopy in 1977.SDS of cas: 322-46-3 This article mentions the following:
A transferable valence force field is developed for application to the out-of-plane vibrations of C6H6, naphthalene, and their aza analogs. Existing vibrational frequency assignments are rationalized and in some cases extensively revised. The mols. treated are quinoline and isoquinoline; 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 2,3- and 2,7-diazanaphthalene; 1,3,5-, 1,3,6-, 1,3,7-, 1,3,8-, 1,4,5- and 1,4,6-triazanaphthalene; and 1,3,5,8-, 1,4,5,8- and 2,3,6,7-tetraazanaphthalene. The assignment of the planar frequencies at 350-1000 cm-1 is also reviewed for these mols. The calculations on the azabenzenes are discussed. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3SDS of cas: 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine derivatives have antitumor, antibiotic, anticonvulsant, antituberculous and diuretic effects as well as kinase, enzymatic and potent tubulin and FtsZ polymerization inhibitory activities. A number of pyrazine-based derivatives were used as dyes or fluorescent probes.SDS of cas: 322-46-3
