Chemistry: Symmetry/Asymmetry

All kinds of symmetry-related problems in organic and inorganic chemistry may be the subject of papers submitted to Symmetry. One of the most relevant fields includes optical activity that is the consequence of a kind of chirality center, such as an asymmetric C atom, while a heteroatom, like P. Atrop isomerism, may also be a reason. The discussion of problems associated with a stereogene center or centers, like the separation of racemates, enantiomer enrichment or separation, chiral induction, diastereomeric transition states, diastereomers or intermediates, asymmetric (enantioselective) syntheses, or any kind of selective syntheses, is welcome. New transition metal complex catalysts comprising optically active P-ligands and the asymmetric reactions that they allow are also of interest.

Another exciting field that may attract papers for Symmetry is X-ray crystallography. These days, single-crystal X-ray analysis is a routine method that not only allows the elucidation of the stereostructures of individual molecules but also gives insights regarding the crystal structures hiding symmetry/asymmetry-related issues.

Last but not least, theoretical calculations may also include symmetry-related problems [1,2,3,4,5,6,7,8].
