29 Si NMR spectra of the O ‐trimethylsilyl (OTMS) derivatives of various methyl α‐ and β‐ D ‐galactopyranosides have been recorded. The effect of changes in the anomeric configuration provides a means of assigning the resonance of the 2‐OTMS substituent. Whereas the signal of the OTMS group attached at the 6‐position can be assigned readily, those of the OTMS group at the 3‐ or 4‐position cannot be assigned unequivocally.
