## Abstract A diad compound 3β(bicyclo[2,2,1]hepta‐2,5‐diene‐2‐methylcarboxylate‐3‐carboxy)‐an‐drost‐5‐en‐17‐one (NBD‐S‐ONE) was synthesized and its photochemistry was examined. Irradiation of NBD‐S‐ONE in acetonitrile at λ > 300 nm selectively excited the keto chromophore. After intersystem crossi
