Manifestation of Strong Quadrupole Light-Molecule Interaction in the SER and SEHR Spectra of Pyrazine and Phenazine
It is demonstrated that explanation of appearance of strong forbidden lines
in the SEHR spectra of pyrazine and phenazine, caused by totally symmetric
vibrations and also other details of their SER and SEHR spectra can be made on
the base of the dipole-quadrupole theory. The main point of this theory is
conception of a strong quadrupole light molecule interaction, arising in
surface fields strongly varying in space near a rough metal surface. Existence
of the pointed lines is a good corroboration of existence of the strong
quadrupole light-molecule interaction.Comment: 31 pages 6 figure
