    the beta phase‚ due to the lack of mechanism‚ there is absolutely no thermal expansion at all. Hence‚ it can also be said that a dynamic instability only exists in the alpha FePO4 and not in the beta FePO4. In addition‚ there is an occurrence of diffraction‚ meaning a mild bending of the structure‚ in the inter-conversion of alpha FePO4 and B-FEPO4 through tetrahedral tilting. FePO4 is

    of monofunctional bidentate Schiff base have been synthesized and characterized through elemental analysis‚ conductance measurements‚ molecular weight determinations‚ UV-visible‚ multinuclear (1H‚ 13C‚ 119Sn) NMR spectroscopy‚ FT-IR‚ X-ray powder diffraction and theoretical calculations. On the basis of these techniques‚ it is proposed that the ligands are bounded to the tin atom through the azomethine nitrogen and carboxylate oxygen. The data reveal that triorganotin(IV) complexes have penta-coordination

    to frequency and the results were discussed. In our present work‚ K2Pb(SO4)2 was synthesized at 80°C using potassium sulphate and lead nitrate of high purity as the starting material. The structural property of the material was studied by X-ray diffraction (XRD). The functional groups present in the material were identified using Fourier Transform Infra-Red (FTIR) Spectroscopy. The thermal behaviour was analyzed by using TG-DSC studies. UV-Vis Spectroscopy and Photoluminescence studies were taken

    3. Result and discussion 2.1 Physicochemical properties The formations of BPM I-III were confirmed by FT-IR‚ powder XRD and SEM studies. 2.1.1 Fourier transform infrared spectroscopy FT-IR spectra of BPM I-BPM III (Fig. 1a-1c) exhibited characteristic absorption bands of CTS ranges from 1637-1639 cm−1 which are attributed to amide I bands (C=O stretching mode along with an N–H deformation mode). Broad bands from 1130-978 cm−1‚ 1131-975 cm−1 and 1131-971 cm−1 were observed for phosphate stretching
