Abstract
We find that at a given temperature the Brillouin linewidths in triphenylphosphite are well described by the two‐parameter expression Bkα, where the scattering wave number k is varied over two and a half orders of magnitude. The data include measurements in all states of the system from low viscosity liquid to a glass; the parameters α(T) and B(T) exhibit extrema at similar temperatures.Keywords
