Qhov sib txawv tseem ceeb ntawm Zeeman effect thiab Paschen Back effect yog tias Zeeman effect cuam tshuam nrog kev sib cais me me piv rau lub zog sib txawv ntawm cov qib tsis muaj kev cuam tshuam, thaum Paschen-Back nyhuv cuam tshuam nrog lub xub ntiag ntawm sab nraud magnetic teb nyob rau hauv uas lub zog. theem ntawm cov atoms tau faib.
Zeeman effect thiab Paschen-Back effect yog cov ntsiab lus tseem ceeb hauv chemistry thiab piav qhia cov qauv sib cais ntawm cov kab spectral.
Zeeman Effect yog dab tsi?
Zeeman nyhuv tuaj yeem piav qhia raws li cov txiaj ntsig ntawm kev faib cov kab spectral mus rau ntau yam khoom nyob rau hauv lub xub ntiag ntawm ib qho chaw sib nqus zoo li qub. Qhov tshwm sim no tau muaj npe tom qab Dutch physicist Pieter Zeeman hauv 1896. Nws kuj tau txais Noble Prize rau qhov kev tshawb pom no. Cov nyhuv Zeeman yog qhov sib piv rau cov nyhuv Stark hauv kev sib cais ntawm cov kab spectral mus rau ntau qhov chaw thaum muaj hluav taws xob, qhov uas nws zoo ib yam li Stark nyhuv hauv kev hloov pauv ntawm cov khoom sib txawv.

Qhov kev ncua deb ntawm Zeeman sub-theem yog qhov ua haujlwm ntawm lub zog sib nqus. Yog li, peb tuaj yeem siv Zeeman nyhuv los ntsuas qhov sib nqus lub zog. Piv txwv li, ntsuas qhov sib nqus lub zog ntawm lub hnub thiab lwm cov hnub qub.
Muaj ntau yam kev siv tseem ceeb ntawm Zeeman nyhuv, xws li nuclear magnetic resonance spectroscopy, electron spin resonance spectroscopy, magnetic resonance imaging, thiab lwm yam. Ntxiv mus, peb tuaj yeem siv nws los txhim kho qhov tseeb ntawm atomic absorption spectroscopy. Tsis tas li ntawd, yog tias cov kab spectral yog kab nqus, ces peb tuaj yeem hu nws ua qhov cuam tshuam Zeeman.
Paschen Back Effect yog dab tsi?
Paschen Back effect tuaj yeem piav qhia raws li tus qauv tsim los ntawm cov hlau nplaum loj uas tuaj yeem cuam tshuam kev sib txuas ntawm lub orbital thiab spin singular momenta, uas ua rau muaj qhov sib txawv ntawm kev sib cais. Cov nyhuv no tau qhia los ntawm ob tus German Physicists, Paschen thiab Ernst Rov qab rau xyoo 1921.
Cov txiaj ntsig no tuaj yeem ua kom dav dav ntawm thaj chaw sib nqus ntawm qhov kev ua tau zoo ntawm Zeeman cov nyhuv zoo dua. Tsis tas li ntawd, cov nyhuv no tau ua tiav tiav nyob rau hauv lub moj khaum ntawm quantum mechanics. Niaj hnub no, qhov kev txhais lus no tshwm sim nyob rau hauv cov phau ntawv classical ntawm atomic lossis molecular spectroscopy.
Qhov txawv ntawm Zeeman Effect thiab Paschen Back Effect yog dab tsi?
Zeeman effect thiab Paschen-Back effect yog cov ntsiab lus tseem ceeb ntawm cov tshuaj hauv chemistry uas piav txog cov qauv sib cais ntawm cov kab spectral. Qhov sib txawv tseem ceeb ntawm Zeeman effect thiab Paschen Back effect yog tias Zeeman effect cuam tshuam nrog kev sib cais me me piv rau lub zog sib txawv ntawm cov qib tsis muaj kev cuam tshuam, whereas Paschen-Back nyhuv cuam tshuam nrog lub xub ntiag ntawm sab nraud magnetic teb nyob rau hauv uas lub zog theem ntawm atoms yog. cais.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm Zeeman effect thiab Paschen Back effect hauv daim ntawv teev npe rau sab sib piv.
Summary – Zeeman Effect vs Paschen Back Effect
Zeeman nyhuv tuaj yeem piav qhia raws li cov txiaj ntsig ntawm kev faib cov kab spectral mus rau ntau yam khoom nyob rau hauv lub xub ntiag ntawm ib qho chaw sib nqus zoo li qub. Paschen Back effect tuaj yeem piav qhia raws li tus qauv tsim los ntawm cov hlau nplaum loj uas tuaj yeem cuam tshuam kev sib txuas ntawm lub orbital thiab spin singular momenta, uas tuaj yeem ua rau muaj qhov sib txawv ntawm kev sib cais. Yog li ntawd, qhov sib txawv tseem ceeb ntawm Zeeman effect thiab Paschen Back effect yog tias Zeeman effect cuam tshuam nrog kev sib cais me me piv rau lub zog sib txawv ntawm cov qib tsis muaj kev cuam tshuam, thaum Paschen Back effect cuam tshuam nrog lub xub ntiag ntawm sab nraud magnetic teb nyob rau hauv uas lub zog theem ntawm atoms. sib cais.
