Application of Vibrational Spectroscopy Supported by Theoretical Calculations in Identification of Amorphous and Crystalline Forms of Cefuroxime Axetil

Figure 3

IR absorption spectra of cefuroxime axetil at room temperature, in polycrystalline powder: (1) crystalline form and (2) amorphous form. The corresponding calculated IR absorption spectra (B3LYP/6-31G(d,p)) were added for comparison (3).
