In the higher excited state, chlorophyll is extremely unstable; it rapidly gives up some of its energy to the surroundings as heat, and enters the lowest excited state, the excited chlorophyll has four alternative pathways for disposing of its available energy: fluorescence, Heat loss, energy transfer, photochemistry; all process takes place in which wavelength,
