Description :
L- Alanine is an α-amino acid with the chemical formula CH3CH(NH2)COOH or C3H7NO2. The α-carbon atom of L- Alanine is bound with a methyl group (-CH3), making it one of the simplest α-amino acids with respect to molecular structure and also resulting in L- Alanine being classified as an aliphatic amino acid. This methyl group of L- Alanine is non-reactive and is thus almost never directly involved in protein function. Amino acids belong to an interesting class of materials which can be used for non linear optical (NLO) applications. The L-isomer is one of the 20 amino acids encoded by the genetic code. It is classified as a non-polar amino acid. L-Alanine.L-Alanine doped potassium di hydrogen phosphate(KDP) single crystals are grown by solution growth technique .slow evaporation technique was adopted for the growth .Due to variation in the doping concentration there is a modification in the growth habit ,nonlinear optical property and mechanical hardness of the doped crystals. The KDP crystal obtained by the above technique were subjected to different characterization analysis .The lattice dimension were determined from the single crystal X-ray diffraction analysis .Fourier transform infrared (FTIR) identified the functional groups and provides information about chemical bonding or molecular structure of material & optical be heavier of the crystals was identified by UV –Vis analysis.Thermogravimetric analysis (TGA) provides the information about physical phenomena such as second order phase transition including vaporization, sublimation ,absorption and desorption
