[In organic nomenclature], atoms or groups are termed cis or trans to one another when they lie respectively on the same or on opposite sides of a reference plane identifiable as common among stereoisomers. The compounds in which such relations occur are termed cis-trans-isomers. For compounds containing only doubly bonded atoms the reference plane contains the doubly bonded atoms and is perpendicular to the plane containing these atoms and those directly attached to them. For cyclic compounds the reference plane is that in which the ring skeleton lies or to which it approximates. When qualifying another word or a locant, cis or trans is followed by a hypen. When added to a structural formula, cis may be abbreviated to c, and trans to t. 1, record 2, English, - cis%2D

[En nomenclature organique], deux atomes ou des groupes d'atomes sont appelés cis ou trans l'un par rapport à l'autre s'ils sont respectivement du même côté ou de part et d'autre d'un plan de référence reconnu commun aux deux stéréoisomères. Les composés dans lesquels une telle relation se rencontre sont appelés isomères cis-trans. Pour les composés dans lesquels la seule origine de cette isomérie est la présence d'atomes doublement liés, le plan de référence contient les atomes doublement liés et est perpendiculaire au plan contenant ces atomes et ceux qui leur sont directement liés. Pour les composés cycliques, le plan de référence est celui qui contient le squelette cyclique ou qui s'en rapproche le plus. Quand il qualifie un mot ou un indice, le terme cis ou trans est suivi d'un trait d'union. Quand ils sont ajoutés à une formule structurale, cis peut être abrégé en c et trans en t. 1, record 2, French, - cis%2D
