<title>Paths of deactivation of excitation of chlorophyll a in various model systems</title>

The photochemical stability of oil from Evening Primrose seeds

“…In the calculations performed it was assumed that in solution the singlet excitation of Car is practically not transferred to Chl [6,7]. Accordingly, the yield of Chl a fluorescence should be approximately the same in the solution of Chl a alone and in the solution of both pigments (because the Car emission can be neglected) [6e8].…”

“…The photochemical role of the various pigments is different, in so far as chlorophylllike pigments enhance the photodegradation of the oil components, whereas carotenoids diminish such processes by quenching the chlorophyll (Chl) triplet states [3], which are very active in photochemical reactions [3e5]. The carotenoids protect Chls against photooxidation, predominantly by quenching their triplet states; they also influence the Chls aggregation [6]. The interactions between these pigments depend on the aggregation of molecules and their mutual orientations [7e9].…”

Resonance energy transfer between FMN molecules in the presence of dimers: A review

“…During the last thirty years, numerous papers, devoted to nonradiative energy transfer between biological molecules and not only between flavins, have appeared [153][154][155][156][157][158][159][160][161][162][163].…”
