Editing Stereocenter (section)

== Configuration ==
Configuration is defined as the arrangement of atoms around a stereocenter.<ref name=":0" /> The [[Cahn–Ingold–Prelog priority rules|Cahn-Ingold-Prelog]] (CIP) system uses R and S designations to define the configuration of atoms about any stereocenter.<ref name=":12">{{Cite journal |last1=Barta |first1=Nancy S. |last2=Stille |first2=John R. |date=1994 |title=Grasping the Concepts of Stereochemistry |url=https://pubs.acs.org/doi/abs/10.1021/ed071p20 |journal=Journal of Chemical Education |language= |volume=71 |issue=1 |page=20 |doi=10.1021/ed071p20 |bibcode=1994JChEd..71...20B |issn=0021-9584|url-access=subscription }}</ref> A designation of R denotes a clockwise direction of substituent priority around the stereocenter, while a designation of S denotes a counter-clockwise direction of substituent priority.<ref name=":12" />
