| dc.description.abstract | The dependence of the absorption of longitudinal ultrasonic waves in single crystals of benzene on the frequency and on the orientation of the crystal was investigated experimentally. Results were compared with the predictions of the resonance absorption theory. Individual crystals were obtained by freezing a melt of highly purified reagent-grade benzene. The crystals were aligned to desired orientations by optical techniques. Absorption coefficients were computed from direct measurements of the attenuation in longitudinal wave propagation at 5, 10, and 15 megacycles. Results were obtained at 255 °K for absorption along each of the principal crystallographic axes and along three offaxial directions. Absorption was found to be a function of crystal orientation, both in magnitude and frequency dependence. The frequency-squared dependence predicted from resonance absorption theory was observed for some, but not all orientations. Results indicate the presence of an additional absorption mechanism. The writers wish to express their appreciation for the patience shown and the assistance and encouragement rendered by Professor 0. B. Wilson of the U. S. Naval Postgraduate School in this work. | en_US |
