Abstract: The proper use of FTIR and laser Raman to study the structure of repeat unit of polyethylene terephthalate (PET) has been presented. A normal co-ordinate analysis of crystalline polyethylene terephthalate (PET) (trans form)  has been carried out. A systematic set of potential constants has been computed using the method of kinetic constants on the basis of C2h symmetry. The potential energy distribution confirms the correctness of the assignments made.
