Which mechanism initiates electron excitation when photon energy matches molecule orbital gap?

A)Resonance energy transfer absorption
B)Franck-Condon principle decay
C)Quantum entanglement tunneling
D)Vibrational relaxation scattering

💡 Explanation

Resonance energy transfer occurs because photon energy matching the orbital energy gap facilitates electron excitation, therefore absorption occurs as the electron jumps to a higher orbital, rather than other loss mechanisms.
