Raman scattering cross sections are computed using a formalism that employs analytical derivatives of frequency-dependent electronic polarizabilities, which treats both off-resonant and resonant enhancement within the same scheme. In the off-resonant regime, Raman scattering into molecular vibrational modes is enhanced by one order of magnitude and shows pronounced dependence on the orientation and the local symmetry of the molecu","authors_text":"Al\\'an Aspuru-Guzik, Dmitrij Rappoport, Michael Stopa, Roberto Olivares-Amaya, Semion K.
