Résumé : Gas chromatography of helicenes and 1,2-diaryl ethylenes. The Kováts retention indices on Silicone OV1 of non-substituted helicenes, aza-helicenes and 1,2-diaryl ethylenes have been determined. Relations between these indices and the molecular structures of these compounds can be deduced. Moreover, series of homologues have been found which allow the indices of still unknown homologous compounds to be predicted. © 1972.
