## 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
