Which mechanism allows electron excitation between mismatched orbitals?

💡 Explanation

Quantum tunneling involves electrons penetrating potential barriers via virtual photons leading to orbital excitation, because the uncertainty principle allows short-term energy non-conservation. Therefore, mismatched orbitals interact via tunneling, rather than through direct overlap, influenced by shielding alone.
