Optical isomers occur in pairs that are nonsuperimposable mirror images of each other, like right- and left-handed gloves. They take their name from their effect of rotating the plane of polarization of a beam of polarized light that is directed through them .... 6, record 1, English, - optical%20isomer

On sait fabriquer les molécules images des précédentes; on trouve effectivement toutes les propriétés rigoureusement identiques, y compris la valeur absolue du pouvoir rotatoire. Seul le signe de ce dernier est inverse. Deux telles substances qui ne diffèrent que par le signe de leur pouvoir rotatoire, s'appellent des antipodes optiques, des inverses optiques, des énantiomères ou des isomères optiques. 8, record 1, French, - isom%C3%A8re%20optique

Énantiomère (n.m.) - (énantiomorphe, inverse optique, antipode optique). Qualifie les deux formes isomères d'un même composé qui, possédant un carbone asymétrique, sont images l'une de l'autre dans un miroir. Les deux énantiomères font tourner le plan de polarisation de la lumière du même angle mais en sens contraire : l'un est dextrogyre (+) l'autre lévogyre (-). Le mélange des deux énantiomères en quantités égales est dit racémique. 9, record 1, French, - isom%C3%A8re%20optique
