Abstract
Knoop microhardness anisotropy on the cleavage plane (100) of single crysta ls of L-arginine hydrochloride monohydrate (LAHCl) and L-arginine hydrobrom ide monohydrate (LAHBr) is reported. The microhardness increases from < 001 > to < 011 > and then decreases to < 010 > orientation. Calculation of You ng's modulus values for (100), (010), and (001) planes of LAHCl and LAHBr s hows that the (100) plane for both crystals has the lowest value of Young's modulus. Moreover, Young's modulus values for all the planes of LAHCl are higher than those of LAHBr. (C) 2000 Elsevier Science Ltd. All rights reser ved.
