Site-selective spectroscopy and level ordering in C-phycocyanin.
In: Chemical Physics Letters, Vol. 143, No. 2: pp. 169-173
We present a combined fluorescence and hole-burning study of the biliprotein C-phycocyanin. Sharp zero-phonon holes compare with a broad structureless fluorescence. This finding is rationalized in terms of the special level structure in this pigment, the fast energy-transfer processes and a lack of correlation of the energies of the emissive states.
