Abstract
Ultrasonic, piezoelectric and dielectric measurements on single crysta ls of (-)-2-alpha-methylbenzylamino-5-nitropyridine (MBANP) are report ed. Longitudinal and transverse velocity measurements in six crystal d irections were used to calculate the 13 elastic constants. Dielectric measurements were carried out in four directions and compared with ref ractive index measurements carried out at optical frequencies. MBANP e xhibited piezoelectric coefficients of similar magnitude to those foun d in lithium niobate. These data are discussed in terms of the intermo lecular interactions occurring in the crystal structure.
