The attenuation of thermally induced sound waves in formamide has been measured by Brillouin light scattering. Solutions of formamide in water, methanol, and ethanol as well as acetamide in water have also been measured as a function of temperature. The spectra are analyzed in terms of an extended hydrodynamic light scattering theory. The bulk viscosity of formamide in the hypersonic frequency region is significantly greater than the shear viscosity.
