## Abstract The recently modified __J__ doubling in the frequency domain method (MJDFDM) allowed the determination of ^4, 5, 6^__J__ in toluene, a series of 4‐mono‐ and 3,5‐disubstituted toluene derivatives, as well as in 4‐picoline. The methyl and aromatic signals were subjected to successive deco

Abstract
The results of FPT/INDO theory together with the observed ^2^J(HH) coupling in benzyl groups (Ph · CH~2~X) leads to a simple equation ^2^J(HH) = A+B cos θ+C cos 2θ where θ is the C.C.C.X dihedral angle, and X = C,H. The extension to other X substituents can be obtained from additivity rules.

## Abstract The additivity of chloro and hydroxy substituent effects on the formyl proton spin‐spin coupling constants with the __meta__ ring proton, ^5^__J__(HH), has been tested with 15 chlorinated benzaldehydes and hydroxybenzaldehydes by multiple linear regression analysis. No general additivit
