Vibrational spectra and structure of some penicillin derivatives. Part III. Amphicillin and carboxybenzylpenicillin
IR spectra of sodium salts and acids of amphicillin and carboxybenzlpenicillin were investigated in the solid state over the 100-200 cm/ sup -1/ region. Interpretation of the spectra and band assignments was made on the basis of both frequency shifts caused by deuteration and the information on penicillin-like antibiotics from previous studies. The molecular configuration of such a type of antibiotics was suggested, based on the position of characteristic amide and carbonyl bands. Lactam-thiazolidine skeleton vibrations are identified and located. The information obtained will be used in studies on ir spectra of the gamma radiolysis products resulting from lactam-thiazolidine antibiotics to define the radiolysis products and the mechanism of decomposition.
