Qhov sib txawv tseem ceeb ntawm isotopomer thiab isotopologue yog tias isotopomer yog cov organic compound sib txawv tsuas yog nyob rau hauv txoj hauj lwm ntawm isotope, whereas isotopologue yog ib pawg ntawm cov tebchaw uas txawv hauv cov isotopic muaj pes tsawg leeg.
Cov ntsiab lus isotopomer thiab isotopologue yog ob nqe lus tseem ceeb hauv cov tshuaj lom neeg. Lawv piav txog qhov sib txawv ntawm ob qhov sib txuas ntawm cov organic sib txuas.
Isotopomer yog dab tsi?
Lub sij hawm isotopomer yog hais txog isomers nrog isotopic atoms uas muaj tib tus lej ntawm txhua tus isotope ntawm txhua lub ntsiab tab sis txawv ntawm txoj haujlwm. Qhov tshwm sim no zoo ib yam li kev cai lij choj isomerism. Qhov chaw isotopic txiav txim siab stereoisomerism ntawm cov molecule. Stereoisomerism yog ib hom isomerism uas isomers muaj tib lub ntsiab lus (muaj tib qhov chaw) tab sis muaj qhov sib txawv ntawm kev taw qhia ntawm cov khoom hauv qhov chaw. Tsis tas li ntawd, lo lus no isotopomer yog thawj zaug los ntawm Seeman thiab Paine hauv 1992 hauv kev sib txawv isotopic isomers los ntawm isotopologues.

Ntxiv mus, hauv NMR spectroscopy, C-12 (qhov ntau tshaj isotope) tsis tsim cov teeb liab, thaum C-13 (tsis muaj isotope ntau dua) tuaj yeem tshawb pom tau yooj yim. Qhov no ua rau cov pa roj carbon isotopomers ntawm ib qho chaw uas yuav tsum tau kawm los ntawm C-13 NMR los txiav txim siab cov pa roj carbon atoms sib txawv uas tshwm sim hauv qhov sib xyaw.
Isotopologue yog dab tsi?
Isopologue molecules yog cov molecules uas txawv ntawm cov isotopic muaj pes tsawg leeg. Cov molecules no muaj tib yam tshuaj formula thiab kev sib koom ua ke ntawm atoms. Txawm li cas los xij, tsawg kawg ib lub atom muaj ntau tus lej ntawm cov neutrons dua li cov niam txiv molecule.
Piv txwv li, dej muaj hydrogen-txog isotopologues.
- Lub teeb thiab dej ib nrab hnyav muaj deuterium isotope hauv qhov sib npaug rau protium
- Hnyav dej nrog ob deuterium isotopes ntawm hydrogen ib molecule
- Hauv dej hnyav hnyav lossis dej tritiated, qee qhov lossis tag nrho cov hydrogen atoms tau hloov nrog tritium isotopes

Hauv isotopologues, cov atoms ntawm cov isotopes sib txawv tuaj yeem tshwm sim nyob qhov twg ntawm cov molecule. Yog li ntawd, qhov sib txawv yog nyob rau hauv net chemical formula. Yog tias muaj cov tebchaw nrog ob peb lub atoms ntawm tib lub caij, nws tuaj yeem muaj ib qho ntawm cov atoms hloov pauv, thiab nws tseem muab tib lub isotopologue.
Qhov txawv ntawm Isotopomer thiab Isotopologue yog dab tsi?
Isopologue molecules yog cov molecules uas txawv ntawm cov isotopic muaj pes tsawg leeg. Isotopomer yog isomers nrog isotopic atoms, nyob rau hauv uas muaj tib tus naj npawb ntawm txhua isotope, tab sis cov isotopes nyob rau hauv ntau txoj hauj lwm. Yog li ntawd, qhov sib txawv tseem ceeb ntawm isotopomer thiab isotopologue yog tias isotopomer yog ib qho organic compound sib txawv tsuas yog nyob rau hauv txoj hauj lwm ntawm isotope whereas isotopologue yog ib pawg ntawm cov tebchaw uas txawv ntawm cov isotopic muaj pes tsawg leeg.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm isotopomer thiab isotopologue hauv daim ntawv teev npe rau kev sib piv ntawm ib sab.
Summary – Isotopomer vs Isotopologue
Cov ntsiab lus isotopomer thiab isotopologue yog ob nqe lus tseem ceeb hauv cov tshuaj lom neeg uas piav txog qhov sib txawv ntawm ob qhov sib txuas ntawm cov organic sib txuas. Qhov sib txawv tseem ceeb ntawm isotopomer thiab isotopologue yog tias ib qho isotopomer yog cov organic sib txawv tsuas yog nyob rau hauv txoj hauj lwm ntawm isotope, whereas isotopologue yog ib qho ntawm ib pawg ntawm cov tebchaw uas txawv hauv cov isotopic muaj pes tsawg leeg.
