The freezing process is studied by quasi elastic light scattering at the solid liquid interface of growing Salol crystals. Depending upon the experimental condition one observes two different dynamical states of the interface. One manifests itself in an oscillating autocorrelation function the other in an exponentially decaying one. Measurements of the frequency of the oscillations as a function of the scattering angle and the laser frequency suggest that the scattered light is Doppler shifted in the first case. In the second case the decay rate (line width) increases with the square of the scattering vector. The results of these measurements are compared with those obtained in a similar experiment performed on ice.
