AlagumariA. 12021131Background and Objective: The single crystal of sodium hydrogen tartrate monohydrate was grown by the slow cooling method recently. In the modern era organic acid-metal base crystals are suitable for the study of their structure and non-linear optical activity. In the present work, few important characterization analyses and detailed discussion of title crystal were reported for the first time using the single diffusion silica gel technique. Materials and Methods: Sodium Meta Silicate (SMS), tartaric acid and acetic acid were the raw materials used in the crystallization. Single crystal with high transparency was obtained from the single diffusion silica gel technique. Results: The crystallographic parameters and space group were determined from the single crystal XRD and all the parameter values were found to be in good agreement with the already reported values. FT-IR and FT-Raman spectroscopy analysis provide pieces of evidence on the structure. The optical transparency range and the lower cut-off wavelength of the material were identified from the UV-Vis-NIR absorption spectrum. Conclusion: Sodium hydrogen tartrate monohydrate crystal belongs to the orthorhombic system with space P212121. Functional groups present in the crystal were identified by FT-IR and FT-Raman spectral analysis. The optical band gap was determined as 5.5 eV, which reveals that the grown crystal is typical of dielectric material. The melting point was found to be 263°C by the capillary tube method.]]>Quasim, I., A. Firdous, N. Sahni, S.K. Khosa and P.N. Kotru,200944539547Sasikala, V., D. Sajan, N. Vijayan, K.
