## Abstract A study is presented of the structural dependencies for scalar __J__‐coupling across four bonds in propanic and allylic systems. Density functional theory (DFT) and finite perturbation theory (FPT) were used to obtain the Fermi contact (FC) contributions to ^1^H,^1^H coupling. Interprot
## Abstract 1,2,3,4‐tetrachloro‐5,6,7,8‐tetrafluoro‐9‐methyltriptycene was studied in NMR spectra at low temperatures where the methyl group dynamics is frozen. Values of ^5^__J__(^19^F,^1^H), ^1^__J__(^13^C,^1^H), and ^2^__J__(^1^H,^1^H) for the individual methyl protons were measured. They are in
