Abstract
Raman scattering from square and cubic site-percolation lattices has been calculated and a linear scaling for the Raman coupling coefficient is found. Our results show the fluctuation origin of Raman scattering, thereby invalidating the models used so far which are based on scaling properties of the local strain and on the existence of a smooth vibrational wave function.Keywords
