Proton NMR data for a number of l-.IZ-4-Y-3,5-dimethylbenzenc?s and l-X-2-Y-4-Z-3,5-dimethylbenzenc?s 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 snbstituents. Thii conclusion was strongly supported by the

## Abstract The proton chemical shifts are reported for monosubstituted naphthalenes, quinolines and quinoxalines. Together with literature data, these chemical shifts are compared with the parent compounds and substituent effects evaluated statistically. The effect of substituents parallels that i
## Abstract Carbon‐13 chemical shift parameters for equatorial and axial substituents in cyclohexane are reported for methyl, ethyl, isopropyl, methoxy and phthalimido substituents. The usefulness of the alkyl parameters is demonstrated by the agreement between calculated and observed ^13^C shifts
