ქიმიის ტერმინთა განმარტებითი ლექსიკონი

Term used by some authorities to refer to stereoisomerism resulting from the arrangement of out- of-plane groups with respect to a plane (chirality plane ). It is exemplified by the atropisomerism of (E)-cyclooctene (chiral plane = double bond and attached atoms) or monosubstituted paracyclophane (chiral plane = substituted ring). The configuration of molecular entities possessing planar chirality is specified by the stereodescriptors Rp and Sp (or P and M).

Synonym: planar stereoisomerism
