How do we determine whether modes in Raman spectroscopy are A1g, B1g, or Eg in catalysts and composites we have synthesized?

José Elias Abrão Neto

It will depend on what you have synthesized. The denomination A1g,B1g etc.. is the group symmetry of your compound. If you have an idea of the molecular geometry you can find what type of symetries it has and with that information you can use a tanabe-sugano diagram to see energy gaps and relate it to your Raman spectra.
