## Abstract The ^1^H and ^13^C NMR spectra of 1,2‐dibromoethane‐^13^C~2~ have been analyzed to determine the magnitude (38·9 Hz) and sign (positive) of ^1^__J__(CC) relative to those of ^3^__J__(HH) (positive). This type of coupling appears to be rather insensitive to the presence of bromine or m
