## 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

✦ Synopsis
m fiial form 21 March 1980 '3C-'3C dlpolar mteraction can lead to strong cross-relaxation effects, in organic sohds. even at natural levels of 13C isotopic abundance. Such an effect observed in hexamethylethane is reported here. Calculated values of the cross-relaxation rate, due to molecular translation and rlgd lattice fhp-flops. agree with the expenmental results.
