## Abstract Substituent shift effects on geminal protons are consistent with cumulative α‐, β‐ and γ‐effects of a long chain substituent, e.g. whereby not only the first, but also the subsequent β‐ and γ‐atoms of the sidechain should be taken into consideration. These shift contributions depend on

✦ Synopsis
Abstract
It is shown that the proton chemical shift may be predicted with fairly good precision for a proton in an ethano fragment carrying a (long) vicinal substituent. Caution must be used however in calculating geminal effects.

## Abstract The hydroxyl proton chemical shift in substituted benzyl alcohols may be used, either at infinite dilution in CCl~4~, or in dilute solutions in DMSO, as a reliable indicator of substituent effects. The sensitivity of the hydroxyl proton to substituents is much greater than that of the m
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
