概要

• 論文の詳細を見る

• The electronic absorption and MCD spectra and phosphorescence spectra at 77 K, in solutions, have been studied by the use of P-P-P-method calculations. The longest-wavelength S–S ππ<SUP>*</SUP> band, near 370 nm, is proved to consist of two ππ<SUP>*</SUP> bands, the <SUP>1</SUP>A<SUB>1</SUB> and <SUP>1</SUP>B<SUB>2</SUB> bands. The nπ<SUP>*</SUP> absorption, and phosphorescence bands in various kinds of solutions are compared in many respects with those of the <I>o</I>-quinones previously studied.
