Objective: To discussed the difference between infrared and Raman characteristic group frequencies of cefalexin,assigned the molecule vibration and identified to associate characteristic frequencies with its characteristic structure. Method: The molecular vibration of cefalexin was detected and measured by FTIR and FT-Raman. Result: These experiment results provide more important information for pharmaceutical synthesis and quality control. Conclusion: Raman spectroscopy is fast,simple,accurate,with automated identification and no sample damage,so it may be an effective identification means in daily inspection in the future.
