Theoretical Investigation of Optical and Mechanical Properties of Sodium Hydrogen Succinate Single Crystal: a Third Order NLO Material

Sodium hydrogen succinate (SHS), an alkali metallo-organic third order NLO single crystals were grown successfully using aqueous solution by slow evaporation technique at room temperature. Single crystal X-ray diffraction analysis reveals that the grown crystal belongs to monoclinic system with space group C2/c. The presence of sodium in the title compound was confirmed by ICP-OES analysis. The existence of proton and carbon peak in the material was detected using NMR analysis. Using optical absorption studies, the theoretical calculations such as refractive index, reflectance, electrical conductivity, electrical susceptibility and optical conductivity of SHS were determined. The mechanical properties like brittleness index, fracture toughness, yield strength and elastic stiffness coefficient were estimated using Vickers microhardness test. The ac, dc conductivity and activation energy of SHS were also found using dielectric studies at different temperatures.
