Proton NMR data for a number of 1-X-4-Y-3,5-dimethylbenzenes and 1-X-2-Y-4-Z-3,5-dimethylbenzenes are presented. The proton chemical shifts of the methyl groups at positions 3 and 5 are mainly affected by the ring current effect of the substituents. This conclusion was strongly supported by the proton chemical shifts calculated using additivity rules.
