Effect of spin-orbit splitting can be observed for sulfur elements and compounds. The user typically observes either splitting between components or asymmetric peak shape due to unresolved doublet, depending on chemical state and/or instrument resolution. S2s peak, like S2p, shows a large ran...

Sulfur belongs to a nonmetallic chemical element (pure product: yellow crystalline solid) under the symbol S. It can actively react with many other elements. It exists in various kinds of forms and compound such as sulfide and sulfate minerals which can be found everywhere around the universe an...
Sulfur was known to the ancients; it is the brimstone of the Bible. It was first recognized as an element in 1777 by A. L. Lavoisier. Properties and Compounds Sulfur is found in Group 16 of the periodic table. It exhibits allotropy. Solid sulfur occurs principally in three forms, all ...

The sulfur-containing amino acids (cysteine and methionine) are generally considered to be nonpolar and hydrophobic. In fact, methionine is one of the most hydrophobic amino acids and is almost always found on the interior of proteins. Cysteine on the other hand does ionize to yield the thiolate...
Inspired by the redox-responsivity of sulfur bonds, selenium (Se), belonging to the same family as S in the periodic table of the elements, has also attracted increasing interest. Selenium is a unique, essential trace element that plays an important role in the antioxidant defense and redox ...
