Abstract : According to the resonance absorption theory proposed by L. N. Liebermann (Phys. Rev. 113:1052, 1959), large acoustic attenuations can occur in molecular crystals as the result of weak coupling among lattice and intramolecular oscillators near resonance. Theoretical and experimental investigations have been undertaken for the purpose of testing this theory. A refinement of Liebermann's original theory is presented and employed to calculate the absorption coefficient for crystalline cyclohexane. The apparatus and techniques utilized to grow large crystals and to measure the absorption are described, and the experimental results are compared to those predicted by the theory. The close agreement between theory and experiment observed in this comparison together with Liebermann's results for benzene offer strong support for the resonance absorption theory. (Author)
