Abstract

The construction of a frequency modulated optic cell and its operation for studying the ultrasonic velocities of cyclohexane, acetone and ethyl alcohol as a function of temperature is described. A description of photon-phonon scattering interactions is presented. The appearance of the intensity distribution of the scattered light is treated, and an analysis of the experimental results is included. The special scattering case of Bragg diffraction of coherent light was used for determining the ultrasonic velocities of cyclohexane as a function of temperature. Ramifications of the Raman-Nath and Bragg diffraction effects are discussed. The relationship vT = 1376.78 - 5.25 T equating the ultrasonic velocity as a function of temperature for cyclohexane to within 0.5% accuracy is empirically derived. The values predicted by this relationship are compared to data reported by other sources, and found to agree within 0.3% with two of the sources.
