The sulphur haze is contentious on photochemical grounds.
This assumption can break down in photochemical reactions and other very fast processes that are started impulsively.
The remainder of the presentation will focus on the photochemical evolution of these materials and astrobiology.
These pigment-protein complexes carry out the initial photochemical electron-transfer reactions of plants and photosynthetic bacteria.
These data will allow us to construct photochemical models, in order for them to be more realistic.
Therefore, photochemical alterations in only a fraction of them do not disturb their biological function significantly.
For the amino acids, the main photochemical degradation process has been shown to be decarboxylation, whereas decarbonylation was observed for peptides.
A photochemical technique to enhance sensitivity of detection of fluorescence resonance energy transfer.
