The average conformations of methyl esters of some aliphatic erythro ‐ and threo ‐dichlorocarboxylic acids in dilute carbon tetrachloride solutions have been determined from the vicinal proton–proton coupling constants and 1 H NMR shifts. The 13 C shift differences between the erythro and threo forms are compared and discussed with regard to the differences in the average conformations.
