Computer models helped reveal one of the mysteries of the Venerian atmosphere

Computer models developed with the collaboration of scientists from Spain and the United States have helped to establish a new option for the formation of specific sulphur particles, probably responsible for the absorption of UV-violet into the Venus atmosphere.

According to scientists, the destruction of sulfur dioxide in excess of the Venerian atmosphere leads not only to conventional atomarial sulphur, but also to allotropic options, including S2, S4 and finally S8, which actively absorbs UV, until recently remains a mystery as to how this process is initiated.

Normally, the formation of S2 comes from a combination of two sulphur atoms, then the pair of S2 becomes S4 and the pair becomes S8. According to scientists, the ring structure of S8 is the most resistant to the destruction of UV, but the process of formation of S2 has been found to be not only through the direct integration of the two sulphur atoms, but also through a much faster reaction of SO and S2O, which in turn is derived from the destruction of SO2 by UV.

According to scientists, computing chemistry is used for the first time to assess which types of reactions are more important than laboratory research. This is a very practical way to study the Venus atmosphere. In addition, real laboratory experiments with elements like sulphur, chlorine, and oxygen present in the Venezuelan atmosphere can simply be unsafe.

According to researchers, "sulphur chemistry" plays a dominant role in the Venus atmosphere and is likely to play a key role in creating the mysterious absorber of UV; moreover, similar computational techniques may be used to understand other chemical processes in the planet's atmosphere.
