Abstract: Graphene, a monolayer of carbon atoms obtained in the laboratory for the first time in 2004, is a very promising material for technological applications. One of the powerful experimental techniques to characterize graphene samples is Raman scattering. The Raman spectrum of graphene consists of several narrow peaks corresponding to emission of one or several phonons. I will discuss theory of Raman scattering in graphene and show that, surprisingly, it carries information not only about phonons, but about the electronic dynamics as well.
