Single crystals of L-Tyrosine hydrochloride were grown by using the submerged seed solution method. The grown crystals were characterized by using single crystal X-ray diffraction. Functional groups and the modes of vibrations were identified by FTIR spectroscopy. The TGA/DTA studies showed that the crystal is stable up to 232°C. Microhardness study revealed that the crystal is a hard material. It is transparent in the entire visible region. The SHG efficiency was determined by the Kurtz and Perry method.
