Signals that confirms the complete hydrolysis of the acetate groups has to be described. Concept introduction: IR spectroscopy is the study of absorption of infrared radiation, which causes vibrational transition in a molecule. Principle of IR spectroscopy Molecules are made up of atoms linked by chemical bonds. The movement of atoms is like spring and balls (vibration). This characteristic vibration is called natural frequency of vibration. C = O bond stretch appear in the range 1750 − 1735 c m − 1 for normal aliphatic ester. Conjugation of C = O stretch with phenyl will appears in the range 1740 − 1715 c m − 1 . O − H stretching signal is broad, at 3400 − 3300 c m − 1
