—The absorption and luminescent properties of two steroids [16‐ketoestrone (I), 5α‐androstane‐3β‐ol‐16,17‐dione (II)] are compared. The behaviour of these compounds which differ only in their A‐ring is significantly different with regard to solvent dependence. The transfer of excitation energy in compound (I) from the phenolic to the diketonic chromophore is studied and compared with data from analogous estrogens. The results obtained in this study indicate a significant long range (presumably conformational) influence of the steroid A and D rings on each other.
