## Abstract Long‐range isotope shifts, Δδ, due to ^37^Cl/^35^Cl and ^81^Br/^79^Br, in the ^19^F NMR spectra of some substituted benzenes are reported. The shifts appear to be invariant to solvent and are additive when the isotopes are in chemically equivalent positions relative to the fluorine site

NMR studies of the 13C isotope shift between and and of the linewidths of the two resolved CH 3 79Br CH 3 81Br resonances were carried out as part of a wider study of the NMR properties of methyl halide molecules. The isotope shift of 1.12 ppb can be readily accounted for in terms of the very slight
## Abstract Splittings in the ^13^C cross‐polarization magic angle spinning spectra of 1, 4‐dibromobenzene and 4‐bromo‐3, 5‐dimethylpyrazole are reported. They arise from (^79,81^Br, ^13^C) interactions influenced by the quadrupolar nature of the bromine nuclei. They are analysed using both ‘invers
