Unveiling epimerization effects: a rotational study of α-d-galactose†
Abstract
By studying its C4 epimer α-D-galactose, the effects of epimerization on the conformational behaviour of α-D-glucose have been unveiled. Using laser ablation of crystalline samples, four conformers of α-D-galactopyranose have been observed, for the first time, in a supersonic expansion by analyzing the Fourier transform rotational spectrum.
