Résumé : The proton chemical shifts of eight benzenoid helicenes, namely: [7], [8], [9], [10], [11], [12], [13] and [14] helicenes, have been assigned by the study of deuteriated or substituted derivatives. The evolution of the chemical shifts with the growth of the helix is discussed. Copyright © 1984 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim
