Which interaction causes increased scattering when photons interact with a molecule having accessible electronic excited states?

💡 Explanation

When the photon energy matches an electronic transition, resonant Rayleigh scattering occurs because the photon excites the molecule to a higher electronic state through orbital interactions. Therefore, resonant Rayleigh scattering dominates leading to increased reflection, rather than Raman scattering which requires different frequency shifts, vibrational excitation requiring molecular vibrations, or surface plasmons needing conducive materials.
