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
and
(or
and
).
