Single crystals of L-Bis Valine selenate (L-BVS) were grown by slow evaporation method. The grown crystals are characterized by single X – ray diffraction analysis. The vibrational frequencies of various functional groups of the crystal are analyzed from FTIR spectrum. The optical transmission of the material is ascertained by recording UV – VIS – NIR spectrum. Micro hardness and dielectric studies were also carried out on the grown crystals. Thermal behavior of the crystals has been investigated by DTA and TGA analysis. The NLO property of the grown crystals has been confirmed by Kurtz-powder SHG test.
