The paper reports a theoretical study of scattering of electrons by edges in graphene and its effect on Raman scattering. First, effective models are discussed for translationally invariant and rough edges. Second, they are used in a calculation of the edge-activated Raman D peak intensity and its dependence on the polarization of the incident/scattered light, as well as on the position of the excitation spot. Manifestations of the quasiclassical character of electron motion in Raman scattering are discussed.
