✦ Synopsis

1.r. and Raman spectra of epi-inositol, muco-inositol, myo-inositol, methyl a-D-glucopyranoside, methyl o-D-glucopyranoside-2,3,4,6,6'-d,, methyl o-o-mannopyranoside, and methyl cY-D-mannopyranoside-2,3,4,6,6'-d, have been recorded in the C-H stretching region. The frequencies of the observed bands are interpreted in terms of a linear equation relating the stretching force constant to the dihedral angle formed by the C-H bond with the lone pairs of electrons on the closest oxygen atom. The usefulness of the equation in the conformational analysis of carbohydrates is considered.
