✦ Synopsis

From analysis of the excitation spectrum of the 625 and (688 \mathrm{~nm}) Пuorescence of dimeric chlorophy Il 4 (Chl a) and the 668 (\mathrm{nm}) Пuorescence of the monomer in the presence or absence of all-trans (\beta)-carotene. It is concluded that resonant energy transfer occurs between (\beta)-carotene and dimeric (\mathrm{Chl}) a This transfer could involve the (2^{1} \mathrm{~A}_{\mathrm{g}}^{-})elecironic state of all-irans (\beta)-carolene which 15 resonant with the second set of pseudo-exciton slates of the dimer
