VCD measures the difference in the circularly polarized light absorption of chiral molecules as a function of their vibrational frequencies. In the context of dioxolanone-type compounds, VCD can be used to analyze the vibrational modes of the functional groups present in these molecules, such as the dioxolane ring. By comparing the experimental VCD spectra with theoretical calculations or reference spectra of known compounds with established configurations, it is possible to assign the absolute configuration (R or S) of the chiral centers in these molecules. VCD is a valuable technique when dealing with small and medium-sized molecules.
