Hloov ua lwm yam pom kev sib hloov rau kev sib hloov , faib pom kev sib hloov los ntawm concentration hauv g / mL thiab txoj kab ntev hauv decimeters (dm).

Yog li ntawd, dab tsi yog tus qauv ntawm kev sib hloov tshwj xeeb?

CRC Phau Ntawv Qhia ntawm Chemistry thiab Physics txhais kev sib hloov Raws li: Rau cov khoom siv kho qhov muag, txhais los ntawm [α]θλ = α / γl, qhov twg α yog lub kaum sab xis los ntawm lub dav hlau polarized lub teeb yog tig los ntawm kev daws ntawm huab hwm coj concentration γ thiab txoj kev ntev l.

Qhov thib ob, dab tsi yog cov units ntawm kev sib hloov tshwj xeeb? Kev sib hloov tshwj xeeb ntawm qhov sib xyaw ua ke yog cov yam ntxwv ntawm cov khoom sib xyaw kom ntev li ntev tau qhov kub thiab txias, yoj ntev ntawm qhov teeb , thiab, yog tias siv cov tshuaj rau kev sim, cov kuab tshuaj tau teev tseg. Cov units ntawm kev sib hloov tshwj xeeb yog degreesmLg-1ua dm-1.

Ib yam li ntawd, koj yuav ua li cas xam enantiomeric ntau dhau los ntawm kev sib hloov tshwj xeeb?

Rau xam tus enantiomeric ntau dhau , koj faib cov pom kev sib hloov los ntawm qhov siab tshaj plaws kev sib hloov ntawm tshaj enantiomer.

Koj txhais li cas los ntawm kev sib hloov tshwj xeeb?

Kev sib hloov tshwj xeeb . Hauv stereochemistry, lub kev sib hloov ntawm ib qho tshuaj compound [α] txhais tau tias yog lub kaum sab xis pom ntawm optical kev sib hloov α thaum lub dav hlau-polarized lub teeb dhau los ntawm cov qauv nrog txoj kab ntev ntawm 1 decimeter thiab cov qauv concentration ntawm 1 gram ib 1 milliliter.
