Abstract
The attenuation of the thermally induced sound wave in the simple carboxylic acids has been measured by using Brillouin light scattering. The maximum in the line width and the dispersion in the frequency shift of the Brillouin bands in formic, acetic, and propionic acid were fit to a three-variable linear-response theory. In the temperature range studied, 20-80°C, the data support the assignment of the relaxation process giving rise to the attenuation as the breaking of the hydrogen-bonded network due to small-angle reorientations.
