Single crystal growth and characterization of the nonlinear optical crystal L-arginine hydrofluoride

In this communication, single crystal growth of the nonlinear optical cryst al L-arginine hydrofluoride C6H14N4O2. HF (here after abbreviated as LAHF) of dimensions up to 20 x 15 x 3 mm(3) is reported. Crystals have been grown by the temperature lowering method and also by slow evaporation method at constant temperature 30 degreesC from its aqueous solution with pH at 2.2. As-grown single crystals were then characterized by density measurement, so lubility test, X-ray powder diffraction studies and infrared (IR) spectrosc opy. (C) 2002 Elsevier Science B.V.
