Electrodynamical Forbiddance of Strong Quadrupole Light-Molecule Interaction in the Methane Molecule and its Manifestation in Surface Enhanced Hyper Raman Scattering Spectra

V. P. Chelibanov, A. M. Polubotko

It is demonstrated in the framework of the Dipole-Quadrupole theory, that strong quadrupole light-molecule interaction, which is responsible for the most enhancement of SEHRS in th…
