Triptycene monodeuterated at the bridgehead position shows in direct and sensitized irradiation a photochemical isotope effect kH/kD=2.2–2.4. From quantum yield of undeuterated, φH,H=0.33 and monodeuterated triptycene, φH,D=0.24 was concluded that the effect stems from differences in the reaction rates and not from differences in the radiationless deactivations.
在桥头位置单氘化的三萜烯在直接和敏化辐射下显示出光化学同位素效应k H / k D = 2.2–2.4。从未氘化的H H,H = 0.33和单氘化三茂铁的量子产率得出,H H,D = 0.24得出结论,其影响源于反应速率的差异,而不是源于无辐射失活的差异。
