When molecules are near-field coupled with optical nanoantennas,

their scattering properties are strongly affected by the radiation

properties of the nanoantenna itself. In surface-enhanced Raman

spectroscopy (SERS) the scattering cross section is greatly en-

hanced. As well, the field orientation and polarization are modified

by the nanoantenna radiation modes. This chapter discusses how

the polarization of the Raman field, inelastically scattered by

molecules in SERS, is modified by the interaction with optical

nanoantennas in a model beyond the E 4 approximation. The polarized SERS intensity is discussed for different nanoantenna

geometries and insight on how to recover information on the Raman

polarizability tensor based on the SERS measurements is given.
