Abstract
^13^C NMR chemical shift assignments for 15 chlorinated diphenyl ethers, containing from two to seven chlorine substituents, were measured and interpreted. Chemical shift data for 12 of these compounds have not been previously reported. Data are based on a number of 1D and 2D experiments performed at 9.4 T.

The 13C NMR spectra of the synthetic chlorins H,(OEC), Ni(TMC) and H,(TPC) have been re-examined. Evidence from single-frequency proton decoupled, proton coupled, and 2D 13C-13C INADEQUATE experiments show that the previous assignments of the meso-substituted chlorins were incorrect. Corrected assig
