Excited singlet state absorption spectra and relaxation kinetics of the azanaphthalenes was written by Boldridge, David W.;Scott, Gary W.. And the article was included in Journal of Chemical Physics in 1986.Related Products of 322-46-3 This article mentions the following:
Picosecond excited-state singlet-singlet absorption spectra (Sn â?S1) and excited-state decay kinetics are reported for several diazanaphthalenes and a triazanaphthalene in room temperature solution New Sn (1nÏ*) state energies were obtained empirically from these spectra. INDO-PSDCI mol. calculations were used to confirm the Sn â?S1 nature of the excited state transitions observed Decay rates were calculated from models based on a semiempirical mol. formalism, and these calculated rates were compared with the observed ones. Agreement of the calculated and observed rates are good except in cases of substantial nÏ*-ÏÏ* mixing of the actual excited states and in a particular case of high mol. symmetry (1,5-naphthyridine). In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Related Products of 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. Pyrazines undergo nearly all of the same reactions as pyrimidines, from nucleophilic substitution (SNAr) to palladium-catalyzed cross coupling reactions.Related Products of 322-46-3
