Abstract

It is intended to achieve a method of separating isomers of chiral substances which is non-contact and does not use a chemical reaction by irradiating chiral substances C with light such as circular polarized light and separating isomers (C1, C2) based on a difference in acceleration thereof, and an apparatus therefor. Separation of isomers of chiral substances of the invention is constituted by including a circular polarized light irradiator (3) which irradiates chiral substances (C) being a mixture of different isomers (C1, C2) released from a molecular beam generator (2) in a vacuum chamber (1) with circular polarized light, and isomer inlets (1a, 1b) which separate the different isomers (C1, C2) of the chiral substances C based on a difference in acceleration thereof.

Description

technical field [0001] The present invention relates to the separation of isomers by irradiating light such as circularly polarized light to a chiral substance so that the radiation force acting on different isomers is different, thereby causing different accelerations for different isomers A method for isomer separation of chiral substances and a device thereof. Background technique [0002] When the real image and the mirror image of a substance cannot be reconciled, the substance is called a chiral substance, and the property is called chirality. Many organic molecules and substances with helical structures have chirality due to their asymmetric stereostructures, and there are isomers with mirror images. [0003] In addition, many naturally occurring polymers such as proteins, sugars, and nucleic acids are composed of one isomer, and these substances play important functions and roles in the maintenance of life activities. Enzymes that catalyze reactions in living organ...
