摘要：

The i.r. and Raman spectra of glycolide, L-lactide and D,L-lactide in the solid state have been investigated in the 4000-100 cm-1 range. An assignment of the fundamental vibrations is given. The Raman spectra of aqueous solutions of these cyclic diesters showed ring-opening and the beginning of polymerization, characterized by the appearance of ester group bands and acid and alcohol end-group bands.
