## Abstract Carbonโ€13, proton coupling constants have been measured in eighteen different 2โ€substituted propanes. ^1^__J__(Cโ€2,H) shows variations similar to those observed previously for monosubstituted methanes. ^2^__J__(Cโ€2,H) is essentially independent of the substituent at Cโ€2, while ^2^__J__(
