The initial assignments for C‐6 and C‐8 in the carbon spectrum of estrone [3‐hydroxyestra‐1,3,5(10)‐triene‐17‐one] were reversed by a subsequent group of investigators. Recent respected reference publications have reproduced these conflicting sets of data, reflecting an uncertainty regarding the correct assignments. The implied question has been answered with the aid of APT, 2D COSY and HETCOR experiments.
