Bulk viscosity of CO${}_2$ from Rayleigh-Brillouin lightscattering spectroscopy at 532 nm

Yuanqing Wang, Wim Ubachs, Willem van de Water

Rayleigh-Brillouin scattering spectra of CO${}_2$ were measured at pressures ranging from 0.5 to 4~bar, and temperatures from 257 to 355~K using green laser light (wavelength 532~nm,…
