Zusammenfassung:Extremely little is known about the factors governing the efficiency of photoionizations. The comparison of propiophenone and γ‐methylvalerophenone highlights that a spontaneous intramolecular transformation accompanied by small structural and electronic changes—the conversion of a triplet moiety into a radical (anion) moiety by a Norrish II reaction—can have a pronounced effect on the electron yield.
