Qhov sib txawv tseem ceeb ntawm ortho thiab para hydrogen yog tias ortho hydrogen molecules muaj spin ntawm ob lub nuclei nyob rau tib qho kev taw qhia whereas para hydrogen molecules muaj spin ntawm ob nuclei nyob rau hauv opposite lus qhia.
Molecular hydrogen nyob rau hauv hydrogen molecule (H 2) tuaj yeem pom nyob rau hauv ob hom xws li ortho hydrogen thiab para hydrogen. Peb categorize lawv li xws li nyob ntawm kev sib haum xeeb ntawm lub nuclear spin ntawm cov atoms. Yog li ntawd, peb feem ntau xa mus rau lawv li spin isomers.
Ortho Hydrogen yog dab tsi?
Ortho hydrogen molecules yog cov dihydrogen molecules uas muaj hydrogen atoms nrog ib tug nucleic spin nyob rau hauv tib txoj kev. Nyob rau hauv lwm yam lus, lub spin ntawm ob atoms yog aligned parallel rau ib leeg. Nws yog spin isomer ntawm para hydrogen.
Daim duab 01: Ortho thiab Para Hydrogen Kev Sib Piv
Txawm li cas los xij, qhov isomer no tshwm sim hauv lub zog siab dua li para hydrogen isomer. Tsis tas li ntawd, hauv NMR spectroscopy, ortho hydrogen tsim ib lub xeev triplet.
Para Hydrogen yog dab tsi?
Para hydrogen molecules yog dihydrogen molecules uas muaj hydrogen atoms nrog ib tug nucleic spin nyob rau hauv opposite lus qhia. Qhov no txhais tau hais tias lub nuclear spin ntawm txhua lub atom nyob rau hauv H 2molecule yog opposite rau ib leeg. Tsis tas li ntawd, nws yog spin isomer ntawm ortho hydrogen. Cov spin atoms ntawm ob lub hydrogen atoms kuj ua raws li antiparallel. Ntxiv mus, qhov isomer no tshwm sim hauv lub xeev qis zog dua li ortho isomer. Tsis tas li ntawd, hauv NMR spectroscopy, qhov hydrogen no muab lub xeev singlet.
Qhov txawv ntawm Ortho thiab Para Hydrogen yog dab tsi?
Qhov sib txawv tseem ceeb ntawm ortho thiab para hydrogen yog tias ortho hydrogen molecules muaj spin ntawm ob lub nuclei nyob rau hauv tib txoj kev uas para hydrogen molecules muaj spin ntawm ob nuclei nyob rau hauv opposite lus qhia. Thaum xav txog lub zog ntawm cov molecules, ortho hydrogen muaj lub zog siab dua li para hydrogen. Ntxiv mus, hauv NMR spectroscopy, ortho hydrogen muab lub xeev triplet thaum para hydrogen muab lub xeev singlet.
Summary – Ortho vs Para Hydrogen
Yeej, ortho thiab para hydrogen yog ob hom H2molecules peb tuaj yeem categorize raws li qhov spin ntawm hydrogen atoms. Qhov sib txawv tseem ceeb ntawm ortho thiab para hydrogen yog tias ortho hydrogen molecules muaj spin ntawm ob lub nuclei nyob rau tib qho kev taw qhia whereas para hydrogen molecules muaj spin ntawm ob nuclei nyob rau hauv opposite lus qhia.
