## Abstract A regular relationship was noted between the influence of substituents on the chemical shifts of the __ortho__ protons in mono‐substituted benzenes and the influence of the same substituents on the protons in the __cis__ relationship in monosubstituted ethylenes.
## Abstract In __para__‐disubstituted benzenes, the effect of one substituent is transferred to the other composite substituent group and its decreased influence on the __ortho__ and __meta__ protons is reflected in their chemical shifts. A graphical presentation of this linear non‐additive depende
