Conclusions
-
1.
The variations in the13C content in molecules of dibenzyl ketone (DBK) on photolysis and in molecules of dibenzyl (a photolytic product of DBK) have been measured.
-
2.
The efficiency of isotope separation is higher, the greater the difference between the effective electron-nuclear interactions in magnetic and nonmagnetic RP. Isotope separation takes place most efficiently at a specific optimal viscosity of the solvent in which the reaction is being carried out.
