11. The exact reverse of radiative recombination is light absorption . 12. Cytosine methylations change the amount of UV light absorption  of the nucleotide base, creating pyrimidine dimers. 13. Hence, the possibility of light absorption  is increased. 14. Proper choice of plasmatic metal nano-particles is crucial for the maximum light absorption  in the active layer. 15. The other laser under research, the excimer laser, relies on ultraviolet light absorption  to blast a clot. 16. The light absorption  capability could be beneficial if it could be adapted to technologies such as solar cells. 17. Following light absorption  photophysical and photochemical conversions occur, which store part of the light energy as chemical energy. 18. Blue light generally causes chloroplasts to seek shelter, while red light draws them out to maximize light absorption . 19. After light absorption  both charge generation as well as charge extraction occurs in the perovskite layer . ]] 20. The light absorption  spectra of these stacked dye aggregates differ from those of the individual monomeric dye molecules.
