AbstractsThe results of the calculations of n-n* transition energies of some free hydrazyl radicals, their ionic forms and initial hydrazines by the SCF-MO-LCAO method with restricted configuration interaction are presented. The comparison of the data obtained with the electronic spectra experimentally found, revealed that the absorption of radical solutions in the visible area was due to the electronic structure of radical molecules, the contribution of ionic forms to the absorption being negligible.On prtsente les rtsultats de calculs des tnergies de transition n-n* de quelques radicaux libres d'hydrazyle, de leurs formes ioniques et des hydrazines initiales par la mtthode

Der Vergleich dieser Resultate mit den Experimentalspektra zeigt, dass die Absorption im Sichtbaren von der Elektronenstruktur der Radikalen herruhrt, wobei der Beitrag der Ionenformen zur Absorption unbedeutend ist.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
