TL;DR: In this article, the magnetic field modulation of the pyrene triplet and pyrene anion concentrations formed through quenching of singlet excited pyrene molecules by N,N -diethylaniline in methanol at room temperature was investigated.

TL;DR: The primary events in bacterial photosynthesis have been studied since it became possible to isolate reaction centers of photosynthetic bacteria, e.g., of Rhodopseudomonas sphaeroides.

TL;DR: In this article, it was shown that the radical ion pair can be formed live for G 10 ns at 300 K and decay by the back transfer of the electron in a blocked reaction center.

TL;DR: The time dependence of the magnetic field effect on radical recombination in solution has been analyzed experimentally and theoretically as mentioned in this paper, and the agreement of this delay-time dependent broadening effect with the theoretical results proves directly the coherence of the spin motion in the radical pairs.

TL;DR: In this article, two-photon excited singlet excitons are quenched by triplets generated via the monophoton absorption of ruby laser emission, which causes a linear increase of the first-order decay rate of the fluorescence yielding a singlet triplet annihilation rate equal to 3 × 10−8 cm3s−1.
