Manifestation of Strong Quadrupole Light-Molecule Interaction in the SEIRA Spectra of Some Symmetrical Molecules
A.M. Polubotko
TL;DR
This paper demonstrates that forbidden lines in SEIRA spectra of certain molecules are due to strong quadrupole light-molecule interactions, explained by the Dipole-Quadrupole theory, revealing new insights into molecular spectroscopy.
Contribution
It provides experimental evidence for the manifestation of strong quadrupole interactions in SEIRA spectra, supported by the Dipole-Quadrupole theoretical framework.
Findings
Forbidden lines explained by quadrupole interactions
Strong quadrupole effects observed in SEIRA spectra
Validation of Dipole-Quadrupole theory for these phenomena
Abstract
It is demonstrated, that the forbidden lines, which were observed in the SEIRA spectra of diprotonated BiPyH22+ and ethylene, adsorbed on Cu, as well as on ethylene, adsorbed on mordenites can be explained on the base of the Dipole-Quadrupole theory of SEIRA and is the consequence of the existence of the strong quadrupole light-molecule interaction.
