✦ Synopsis

Sugar osazones (1,2) and their acetates have circular dichroism spectra with multiple Cotton effects, showing three typical bands. Band I is located between 340 and 420 nm, with a negative Cotton effect, when the C-3 hydroxyl is to the e in the Fischerformula. Band II is located between 240 and 340 nm. and shows two maxima with inverse Cotton effect compared to the Cotton effect of Band I. Band III is located between 240 and 230 nm, and shows a reversed Cotton effect with regard to band II. If the C-3 hydroxyls are
