Accessory pigments transfer their energy to chlorophyll molecules through

Accessory pigments transfer their energy to chlorophyll molecules through Resonance.
It then transfers captured light from one pigment to the next as resonance energy, passing energy from one pigment to the other until reaching the special chlorophyll molecules in the reaction center.
Chlorophyll also transfers resonance energy in the antenna complex, ending in the reaction center where specific chlorophylls P680 and P700 are located.
