STUDIES ON GROWTH AND CHARACTERIZATION OF SINGLE CRYSTAL L-HISTIDINE DI PICRATE

Abstract

Single crystals of pure L-Histidine Di Picrate (LHDP) have been grown by slowevaporation technique at room temperature. The crystalline nature of grown crystal wasestablished by powder X-ray diffraction analysis (XRD). The structure of the grown crystaldetermined by X-ray diffraction analysis reveals that it belongs to the monoclinic system. Thefunctional group of the mature crystals was found by FTIR analysis. The spectral bands havebeen compared with similar complexes using the FTIR spectrum in the range 400-4000 cm-1.The UV-Vis study was performed to know the optical behavior of the grown crystals. Theoptical transmittance of the spectrum of solid material was measured in the range of 190 to 800nm. The crystal shows a good transmittance in the visible region. The transmittance above 74%is observed from 354 to 800 nm, which clearly shows the crystal possesses good opticaltransparency for the second harmonic generation.
