We measured the Raman scattering of graphene deposited nanohole arrays. As the sample was azimuthally rotated, periodicities of 7.5° and 5° were revealed for the 2700cm-1 and 1600cm-1 Raman lines of graphene, respectively. This is contrary to the scattered laser line azimuthal symmetry of 30° for the hole array alone. When a reference dye (stilbene) was deposited on the graphenated platforms, its Raman peak shifted as a function of incident (tilt) angle; this was contrary to the unshifted 1600cm -1 peak of graphene itself. The data suggest strong coupling between the molecular vibrations as portrayed by Raman spectra and surface plasmon polariton waves propagating along the graphene surface.
