Abstract: The method for determining piezoelectric coefficients based on synchrotron radiation x- ray multiple diffraction ( Avanci et al 1998 Phys. Rev. Lett. 81 5426) has been used in the case of a single crystal of the amino acid L- histidine center dot HCl center dot H(2)O. The method relates the E- induced strain with the angular shift in the multiple diffraction peak position. Thus, it allowed us to determine all three (d(14) = 2.25( 9) x 10(-10) C N(-1), d(25) = 4.1( 5) x 10(-11) C N(-1) and d(36) = 2.3(2) x 10(-10) C N(-1)) piezoelectric coefficients of L- histidine center dot HCl center dot H(2)O, using the ( 10 0 0) and ( 0 0 4) primary reflections.
