This study obtained the normal Raman and surface-enhanced Raman scattering (SERS) spectra of flavanthrone and indanthrone at several excitation wavelengths.
Abstract
The spectral assignments were aided by density functional calculations. Since both molecules have very high symmetry (C2h) including a center of inversion, the researchers expected that the modes of u symmetry would be forbidden in the normal Raman spectrum; however, proximity to the surface caused special SERS enhancement of several of the bu modes, along with somewhat weaker enhancement of the au and bg modes.
