“…The position of the Soret band for the monohydrate complex is at 426 nm. Although two-photon induced blue fluorescence from solutions containing this complex could not be detected, the Stokes shift for the penta-coordinated lutidine (see above) and other complexes (33,34) is between 11 and 14 nm. We predict for the monohydrate complex an electronic orgin between 431 and 433 nm.…”

. J. Chem. 66, 1728 (1988).We report the wavelength-selective Raman and fluorescence spectra of monomeric and aggregate species of chlorophyll a in solution. The excitation profile for the molecular emission of the various chlorophyll complexes permit the construction of part of the electronic energy level diagram. For aT-shaped dimeric chlorophyll a , pseudo-exciton splittings of 667 cm-I in the Soret and 397 cm-' in the Q, bands are obtained.

Pulsed laser-induced Raman spectra of dimeric chlorophyll u in the solvent hexane are reported where the wavelength of the exciting radiation is in resonance with the position of the Soret band of the solute. As a result of the Occurrence of effective population saturation of nanosecond-and picosecond-lived S, and S, excited states of the dimer, changes take place in the absorption spectrum of the irradiated part of the solution from which Raman emission of the solvent occurs. The intensity of the observed Raman bands of hexane of different shifts are influenced in a different way by the change in the transmission of the medium. A correlation is made of these changes and the said Raman intensities.
