Abstract

Substituent effects upon ^3^J(FF) are demonstrated to be additive, and a previous analysis of ^4^J(FF) and ^5^J(FF) in polysubstituted fluorobenzenes is updated.

## Abstract The aromatic ^1^H NMR shifts of __ortho__‐disubstituted benzenes were used to derive 285 pair‐induced chemical shifts (pairwise corrections) for vicinal pairs of the substituent set (F, Cl, Br, I, NH~2~, NHCOMe, NO~2~, OH, OMe, Me, CHO, COMe, CN, Ph). Using these parameters and a simple
