## 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

## Abstract Carbon‐13 NMR spectra of some polychlorinated 2‐phenoxyphenols have been obtained. The substituent chemical shifts obtained by varying the chlorine substitution pattern of one ring are very similar to those reported for the corresponding diphenyl ethers. Thus, the replacement of a 2‐chl
