11. Two gyrotropic materials with reversed rotation directions of the two principal polarizations are called optical isomers . 12. Would that create an optical isomer ? 13. He wasa interested in optical isomers . 14. The ( + )-form, or dextrorotatory form, of an optical isomer does the opposite. 15. I'm more interested in the geometric isomers, but would there be optical isomers as well? 16. In the 1920s, both methamphetamine and the dextrorotatory optical isomer of amphetamine, dextroamphetamine, were synthesized. 17. In this system too the presence of enantioenriched catalyst drives the reaction towards one of the two possible optical isomers . 18. The ( " )-optical isomer is one of the organic compounds responsible for the typical patchouli scent. 19. The other methadols ( acetylmethadol, methadol & c ) have at least four optical isomers ( see Orlaam ). 20. The mirror images of a chiral molecule / ion are called enantiomers or "'optical isomers " '.
