The relative stabilities of isomeric 9,9-dimethyl-10-R- and 9-R-9,10-dimethylphenanthrenyl, as well as of 3-R-2,3-diphenylbutan-2-yl and 1-R-2-methyl-1,2-diphenylpropan-1-yl cations, were determined in terms of the density functional theory. The equilibrium isomer ratio was found to depend to an appreciable extent on steric requirements of the substituents.
