Time-resolved fluorescence spectroscopy and photolysis of the photoreceptor blepharismin.
This analysis suggests that the excited state of the shorter wavelength-absorbing form of blepharismin undergoes primary photoprocess faster than that of the free parental chromophore hypericin. Expand
Structure and function of the photoreceptor stentorins in Stentor coeruleus. II. Primary photoprocess and picosecond time-resolved fluorescence.
Results are suggestive of proton dissociation as a primary photoprocess from the excited state of stentorin II, and the fluorescence emission spectrum was time-resolvable in the picosecond time scales. Expand
Primary photoprocesses of phytochrome. Picosecond fluorescence kinetics of oat and pea phytochromes.
Comparison of the fluorescence decay data and the picosecond time-resolved fluorescence spectra suggests differences in conformational flexibility/heterogeneity among the preparations of the monocot vs dicot phy tochromes and the full-length native vs the amino terminus truncated phytochromes.

Energy migration in allophycocyanin‐B trimer with a linker polypeptide: Analysis by the principal multi‐component spectral estimation (PMSE) method
Energy migration processes in allophycocyanin‐B trimer with a linker polypeptide were analyzed using the principal multi‐component spectral estimation (PMSE) method, which does not require assumptionExpand
Initial spectroscopic characterization of the ciliate photoreceptor stentorin.
Thepicosecond time-resolved fluorescence study revealed that the short picosecond emission component was the predominant emitting species in stentorin-2B and -2, followed by longer decaying species, and the possible mechanism for the primary photoreaction appears to involve electron transfer coupled with proton transfer.

Excitation delocalization and relaxation in linear and circular arrays of porphyrins
Photophysical processes such as excitation energy transfer and electron transfer are expected to occur very fast in organized molecular systems in which reactant molecules are arranged with closeExpand
