Power spectrum of coherent Rayleigh-Brillouin scattering in carbon dioxide
- 1. Department of Mechanical and Aerospace Engineering, Princeton University, Princeton, New Jersey 08540 (United States)
Description
We show in this note that, in the coherent Rayleigh-Brillouin scattering (CRBS) experiment [X. Pan, M. N. Shneider, and R. B. Miles, Phys. Rev. A 69, 033814 (2004)], the vibrational modes of the CO2 molecules are frozen. When the gas dynamic parameters are chosen accordingly, the model predicts a line shape that matches with the experimental data. Fitting the theoretical curve to the CRBS data represents a method to measure the speed of high-frequency sound, bulk viscosity, and the rotational relaxation time of molecular gases
