The infrared spectroscopy of carbamazepine polymorph III cocrystals showed distinct shifts in the inherent bands for Carbamazepine drug. Presence of additional bands at wavenumbers other than those for Carbamazepine drug and the coformer were observed thus indicating the formation of a new cocrystalline compound.[Figure 5(a d)] The characteristic band for –NH valence vibration at 3462 cm-1 was found to be elongated and shifted at 3477 cm-1
