The photosynthetic machinery emits a fraction of absorbed light as a highly informative
waste process. The emitted light can be observed as prompt fluorescence during …

Absorption, fluorescence, delayed luminescence and photoacoustic spectra have been
measured to learn about the radiative and non-radiative processes in two porphyrins:(4-N …

The spectroscopic features of bacteriochlorophyll c and bacteriopheophytin c in a nematic
liquid crystal matrix have been investigated. Absorption, circular dichroism, fluorescence …

Energy taken up by light absorption of the leaf pigments is transformed in the process of the
photosynthetic quantum conversion into photosynthesis, chlorophyll fluorescence and …

The spectral properties of tetrapyridyl porphyrin covalently linked to polymer and copolymer
of porphyrin–viologen in dimethylformamide solutions were compared. Many more viologen …

The method of measurements of the action spectra of photopotential generation using a
modulated acting light beam was elaborated and applied to two systems: the solutions of …

Chlorophyll b (Chl b) in model systems occures in several forms. The relationship between
these forms and the forms occurring in organisms is not yet clear. Chl b aggregation has …

Light harvesting peripheral complexes (LH2) and carotenoids free-reaction centres were
isolated from purple photosynthetic bacteria Rhodospirillum molischianum and Rhodobacter …

The review summarizes results concerning photosynthetic systems with chlorophylls and
carotenoids obtained by means of spectral methods such as polarized radiation …

Changes in the yield of the fluorescence emitted by pigments of photosynthetic organisms
could be used for the establishment of the presence of some toxic substances. The presence …
