Abstract: Single crystals of L-Proline Succinate (LPS) were grown by slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to monoclinic crystal system. The optical transmission study reveals the transparency of the crystal in the entire visible region and the cut off wave length has been found to be 210nm. The optical band gap is found to be 5.90eV. The transmittance of L-Proline succinate crystal has been used to calculate the refractive index (n), the extinction coefficient (K) and the real (εr) and imaginary (εi) components of the dielectric constant. Mechanical strength of the grown crystal was analyzed using Vickers microhardness tester. Nonlinear optical property of the crystal was confirmed by Kurtz Perry powder technique. Dielectric constant measurements were carried out at different temperatures. Some fundamental data such as valence electron plasma energy, Penn gap, Fermi energy and electronic polarizability of the grown crystal have been estimated. Photoconductivity measurements carried out on the grown crystal reveal the negative photoconducting nature.
