β¦ Synopsis
The effect of substitution of hydrogen by deuterium in some aromatic compounds on product distributions in the meta photocycloaddition to al kenes was investigated. The isotope effects found are in agreement with a polar mechanism.

## Abstract The ^3^Ξβdeuterium isotope effects of partially and fully deuteriated __tert__βbutyl groups on the ^13^C NMR spectra of __tert__βbutylbenzene and derivatives are discussed in detail. It is shown that they correlate with the chemical shift of Cβ1 of the aromatic ring. It has been demonst
