Spectroscopic analysis of conducting polymeric material helps to reveal valuable information about the complex formation of metal(Li,Zn,Al etc.)with ligand i.e. polymer(Polyaniline,Polyethylaniline,Polymetylaniline,Polypyrrolidone etc.).Various spectroscopic technics may be used in this manner such as Infra Red spectroscopy,X-ray Diffraction technich ,UltraViolet spectroscopy etc.In this paper Infra Red spectroscopy and X-ray Diffraction technich have been used to analyse the complexation and conducting behaviour of the polymeric material which can be used in rechargeable batteries.Infrared spectroscopy deals with various bands which correspond to the charecteristic functional groups and bonds present in polymeric substances .In other words Infrared spectoscopy has been used for assigning the binding sites in metal : polymer complexes.A critical comparision of the structurally important IR absorption bands of each polymer and that of its complexes with Zn(II) and Al (III) metal ion has been reported. In the X-ray analysis of polymers the diffraction spots are board and diminish rapidly with increasing diffraction angle .X-ray spectroscopy, like optical spectroscopy is based upon measurement of emission absorption scattering fluorescence and diffraction of electromagnetic radiations. Such measurements provide much useful information about the composition and structure of matter6,7,8 To study the structural properties of polymeric material X-ray diffraction measurements are performed through the interaction of X-ray the structure of the compound may be thoroughly investigated. The X-ray diffraction theory based on single crystals of low- molecular weight substances is not applicable in the explicit treatment of polymer samples. There are a few studies in this direction 9, 10, 11 X-ray diffraction formulas are sorted to kinds, A and B as follow – (A) X-ray diffraction intensity by an infinitely large crystal. (B) X-ray diffraction intensity by a finitely large crystal. X-ray studies of Polymers and their complexes have been done.
