Abstract: Previous work employed X-ray three-beam diffraction techniques to obtain part of the L-arginine hydrochloride monohydrate (L-AHCL.H2O) piezoelectric coefficients, namely d21, d22, d 23 and d25. Those coefficients were obtained by measuring the shift in the angular position of a number of secondary reflections as a function of the electric field applied in the [010] piezoelectric direction. In this paper a similar procedure has been used to measure the remaining four piezoelectric coefficients in L-AHCL.H2O: with the electric field applied in the [100] direction, d14 and d36 were measured; with the electric field applied in the [001] direction, d34 and d36 were obtained. Therefore the entire piezoelectric matrix of the L-AHCL.H2O crystal has been successfully measured. © 2006 International Union of Crystallography Printed in Great Britain - all rights reserved.
