We successfully grown the high-quality Sodium Mesitylene Sulfonate (SMS) single crystal using slow evaporation method at room temperature. The crystal has been analyzed using single crystal XRD and it belongs to the monoclinic structure with C2 space group suggesting data repeated after 180º rotation, the lattice parameters are a=8.6926 Å, b= 7.3679 Å, c=16.4519 Å and the angle α=γ=90º, β=103.79º. Functional groups and molecular analysis were identified using Fourier infrared and NMR spectroscopy. We report the optical properties using terahertz time-domain spectroscopy (THz TDS) in the range of 0.2-2.5THz. Electronic calculations were performed in the DFT framework in Vienna Ab initio Simulation Package (VASP).
