摘要: Abstract The CASSCF method was used to reveal the structure of anion-radical (AR) and dianion (DA) 1,3-dinitrobenzene in ground lowest excited states. calculations indicate presence two asymmetric (2A″) one C2v symmetric (2A2) structures AR. AR-2A″ is 4 kcal/mol more stable than AR-2A2 configuration. In contrast AR, DA triplet (3B1) singlet (1A1) states characterized by structure. wavefunction state biradical nature singlet–triplet splitting for equal 2 kcal/mol.
