Some Aspects of the Photochemistry of Benzene‐d<sub>1</sub>

The photochemistry of the di‐deuterated benzenes has been examined in the vapour phase over the wavelength range of 245 to 270 nm. The sensitized emission of biacetyl technique was used to obtain the triplet yields. The sums of the singlet and triplet yields for all three molecules were found to be unity between 255 and 265 nm. – Phosphorescence lifetimes in EPA and methylcyclohexane glasses have been recorded and found to be non‐exponential. – Mechanisms consistent with the experimental observations are presented and various rate constants have been examined.
