Enantiomeric tshaj (ee): Ua tshaj ntawm ib enantiomer tshaj lwm yam hauv a sib tov ntawm cov enantiomers . Qhia ua lej: enantiomeric ntau dhau =% of major enantiomer -% ntawm me me enantiomer . Piv txwv: A sib tov muaj li ntawm 86 % R enantiomer thiab 14% S enantiomer muaj 86 % - 14% = 72% ee.

Dhau li ntawm no, dab tsi yog qhov zoo enantiomeric tshaj?

Enantiomeric tshaj . Ib tug racemic sib tov muaj ib tug ee ntawm 0%, thaum ib tug kiag li ntshiab enantiomer muaj 100%. Ib qho piv txwv nrog 70% ntawm ib qho enantiomer thiab 30% ntawm lwm tus muaj ee ntawm 40% (70% - 30%).

Ib sab saum toj no, puas yog optical purity tib yam li enantiomeric tshaj? Lub sijhawm no, " enantiomeric ntau dhau ", los yog "e.e." luv luv, yog sib npaug rau cov kho qhov muag purity thiab tau siv ntau zaus rau kev nthuav qhia cov enantiomeric purity ntawm cov khoom ntawm ib qho kev sib tov. Cov ib yam yuav muaj tseeb rau ib optically ntshiab tov ntawm l- enantiomer : 100% e.e.

Ua li no, koj yuav nrhiav tau qhov enantiomeric piv li cas?

Rau xam tus enantiomeric cov khoom tshaj, koj faib qhov pom kev sib hloov los ntawm qhov siab tshaj plaws kev sib hloov ntawm qhov tshaj enantiomer . Peb ua tau xam feem pua ntawm txhua tus enantiomer raws li tau piav nyob rau hauv lo lus nug Socratic no. Peb muaj 34% enantiomeric cov khoom tshaj (-).

Polarimeter ua haujlwm li cas?

A Polarimeter ua haujlwm los ntawm ci ci monochromatic lub teeb los ntawm ib tug polarizer, uas generates ib tug beam ntawm linearly polarized lub teeb. Lub teeb polarized yuav tig tom qab nws dhau los ntawm a polarimetry cell uas muaj cov qauv.
