π-Electronic structures of 5<I>H</I>,11<I>H</I><SUP>+</SUP>-cyclohepta[<I>b</I>]quinoxalinium ions and their O- and S-analogues were elucidated by means of <SUP>1</SUP>H and <SUP>13</SUP>C NMR spectra, electronic spectra, and theoretical calculations. Consequently, it was shown that these compounds had very stable aromatic characters with positive resonance energies and that the 6π-tropylium-6π-benzonoid form plays an important role for the π-conjugation structure.
