ResumoAbstract The chemical shifts of 298 naturally occurring and synthetic compounds containing the indole chromophoric group are listed. Substituent effects on 13 C chemical shifts (SCS) induced by substitution on the heteroaromatic five‐membered ring are discussed. The data provide a reference set for future 13 C NMR investigations and highlight the need for unambiguous experimental evidence to resolve controversial assignments for differently substituted representative indole derivatives. Many original assignments have been changed, and values not considered to be unambiguously assinged are delineated. The 1 J (CH) values for the parent indole were measured.
