Ž . Ž . We discovered a remarkable effect: spectral diffusion SD induced by energy transfer ET , here called ETTMSD. The X Ž . Ž . ‘effective’ homogeneous linewidth G of the S §S 0–0 band of free-base chlorin H Ch in polystyrene PS was hom 1 0 2 followed as a function of concentration and excitation wavelength by hole-burning. The results cannot simply be explained Ž . X by Forster’s ET mechanism: 1 the increase of G towards the blue is larger than expected and follows an S-shaped ̈ hom Ž . X… CONTINUE READING
