A nonlinear optical crystal of L‐lysine monohydrochloride dihydrate (L‐LMHCl) was grown by slow evaporation solution growth technique using deionised water and mixed solvents of deionised water and ethanol. The functional groups and vibrational frequencies were identified using FTIR and FT‐RAMAN spectra analyses. Also, the presence of hydrogen and carbon atoms in the grown sample was confirmed using proton and carbon NMR spectra analyses. Using TG‐DTA analyses, the decomposition temperature was obtained. Transmittance of the grown crystals was analysed using UV‐visible spectrum. The mechanical strength of the grown crystals was found using Vicker's microhardness tester.
