Which mechanism explains electron excitation when specific photons interact with ruthenium complex orbitals?

💡 Explanation

When photon energy matches orbital gap, the Frank-Condon principle explains electron excitation because it describes transition probability based on overlap. Therefore, option C describes correct excitation, rather than other non-emissive relaxation mechanisms under light irradiation.
