Photolysis of 4‐acetyl‐4‐ethoxyformylcyclohexanone, 4‐acetyl‐4‐phenylcyclohexanone and 1‐acetyl‐1‐phenylcyclohexane in deuteriochloroform using a high pressure Hg—Xe lamp showed unusual polarizations. The results are explained by the formation of a singlet exciplex of the ketone with deuteriochloroform and the photoaddition of deuteriochloroform to the ketone.
