Query: Analysis of Peculiarities of the SEHRS Spectrum of - Bipyridine Molecule
  on the Base of the Dipole-Quadrupole Theory   The SEHRS spectrum of 4,4' Bipyridine is analyzed on the base of the Dipole
Quadrupole theory. It is demonstrated that there appear strong lines caused by
vibrations transforming after a unit irreducible representation of the D2
symmetry group. which is most probably describes the symmetry properties of the
molecule. These lines are nearly forbidden for the molecule, adsorbed on rough
metal surface. Appearance of these lines is associated with a strong quadrupole
light molecule interaction, which exists in this system. In addition, there are
lines, caused by contributions from both the vibrations transforming after the
unit irreducible representation A and the representation B1, which describes
transformational properties of the dz component of the dipole moment, which is
perpendicular to the surface. This result is associated with the specific
geometry of the molecule, when the indicated vibrations can be nearly
degenerated and cannot be resolved by the SEHRS spectra analysis. Analysis of
the SEHRS spectra for the possible geometry of the molecule with the D2h
symmetry group leads to similar results. This issue is in a full coincidence
with the results of the SEHRS Dipole Quadrupole theory.
