L-arginine Maleate Dihydrate (LAMD)
L-Arginine is one of the essential amino acids widely distributed in biological substances. It forms a number of salts with organic and inorganic acids showing non-linear optical properties. L-Arginine maleate dihydrate (LAMD, C6H14N4O2,C4H4O4,2H2O) is one of these L-arginine salts which is a complex of strongly basic amino acid, carboxylic acid and provides useful information in relation to molecular interaction in present day biological systems and to prebiotic self-organisms. It is also a nonlinear optical material with second harmonic generation efficiency 1.68 times that of KDP. LAMD crystals are grown from solution by solvent evaporation; they belong to the triclinic space group P1.
