Growth and Characterization of L-Alanine Crystals using FT-IR, UV Visible Spectra

P. Anitha, N. Muruganantham

Abstract: The L-alanine family crystals such as pure L-Alanine, hydrochloride (HCl) mixed L- alanine, potassiumchloride (kcl) mixed l-alanine and potassium dihydrogen phosphate (kdp) mixed l-alanine have been successfully grown from the aqueous solution by slow evaporation method at room temperature. The grown crystals FT-IR spectral studies were recorded for each sample and the molecular vibrational frequencies confirmed with the standard frequencies. The optical transparency was found out for each crystal by recording the UV-Visible spectrum.
