Spectral Analysis of Pellicillin G

Penicillin was the first antibiotic used by doctors. The discovery of penicillin was one of the great achievements of mankind, this drug saved millions of lives. The discovery was made by accident in 1928, by the Scottish bacteriologist Alexander Fleming. In this article we determined the composition of penicillin G by FTIR spectroscopy using a Bruker spectroscope. The spectrum of penicillin G contains bands between the wave numbers 1700cm-1 and 3500cm-1. Penicillin drugs contain bands due to vibration of the β-lactam carbonyl, side amide bond and ionized carboxylate group.
