Abstract:
(12/12)CASPT2, (16/14)CASPT2, B3LYP, and CCSD(T) calculations have been carried out on 1,8-Naphthoquinone (1,8-NQ), to predict the low-lying electronic states and their relative energies in this non-Kekulé quinone diradical. CASPT2 predicts a 1 A1 ground state, with three other electronic states-3 B2 , 3 B1 , and 1 B1 -within about 10 kcal/mol of the ground state in energy. On the basis of the results of these calculations, it is predicted that NIPES experiments on 1,8-NQ •- will find that 1,8-NQ is a diradical with a singlet ground state. © 2018 Wiley Periodicals, Inc.
