title: Crystal growth and comparative studies of XRD, spectral studies on new NLO crystals: L-Valine and L-valinium succinate.
abstract: Nonlinear optical single crystals of L-valine and L-valinium succinate were grown by slow evaporation solution growth method using water as the solvent. Purity of crystals was increased by the method of recrystallization. The grown crystals were analyzed by the single crystals X-ray diffraction pattern which proved that LVS belongs to orthorhombic crystals system. The presence of functional groups and modes of vibrations were identified by FT-IR spectroscopy. The chemical structure of crystals was established by FT-NMR technique. The transmission range of grown crystals was identified by UV-vis-NIR. The transmission region of LVS was more effective than LV which could be used for NLO applications. The nonlinear optical property of the grown crystals was confirmed by second harmonic generation test which shows the suitability of NLO applications.
