Single crystals of Ammonium chloride doped with Urea an organic material: have been grown by slowevaporation technique at room temperature.The crystalline nature of grown crystal was confirmed by microhardness Analysis. The functional group of the grown crystals was found by FTIR analysis. The spectral bandshave been compared with similar thiourea complexes using the FTIR spectrum in the range 400-4000 cm-1. TheUV- Vis study was performed to know the optical behavior of the grown crystals.
