Abstract:
Inelastic light scattering measurements of capillary wave frequency and damping in the kHz
range for several solutions of sodium carboxymethylcellulose in redistilled water are reported. The
capillary waves were thermally excited and had extremely low amplitudes. Light beating spectro
scopy was used. For these solutions the capillary wave damping was very much lower than expected
from hydrodynamic theory. A surface zone theory is proposed to interpret the experimental results.
