Peb rov hais dua tias thaum ob lossis ntau lub zog muaj peev xwm txav ze rau ib leeg, lossis tseem hla, qhov kwv yees Yug-Oppenheimer tawg, thiab ib qho yuav tsum poob rov qab rau ntawm qhov sib npaug sib npaug..
Yug-Oppenheimer approximation yog dab tsi?
Qhov kev tawg ntawm Yug-Oppenheimer kwv yees: qhov kev vibration-rotation hamiltonian zoo rau lub diatomic molecule. Ib qho zoo vibration-rotation hamiltonian rau hauv av hluav taws xob lub xeev ntawm diatomic molecule yog muab los.
Dab tsi yog qhov tseem ceeb ntawm Born-Oppenheimer kwv yees thiab thaum twg qhov kev kwv yees no tawg?
Kev kwv yees Yug-Oppenheimer yog qhov kev xav tias cov hluav taws xob hluav taws xob thiab cov lus tsa suab nuclear hauv cov molecules tuaj yeem sib cais. Nws ua rau lub molecular nthwv dej muaj nuj nqi nyob rau hauv cov nqe lus ntawm electron txoj hauj lwm thiab nuclear txoj hauj lwm.
Dab tsi yog qhov tseem ceeb ntawm Born-Oppenheimer kwv yees?
Kev kwv yees Yug-Oppenheimer yog ib qho ntawm cov ntsiab lus tseem ceeb hauv qab cov lus piav qhia ntawm quantum xeev ntawm molecules. Qhov kev kwv yees no ua rau nws tuaj yeem cais qhov kev txav ntawm lub nuclei thiab cov lus tsa suab ntawm cov electrons.
Dab tsi yog qhov txwv ntawm Born-Oppenheimer kwv yees?
Thawj BO txoj hauv kev muaj qee yam kev txwv: • Lawv suav tias tsuas yog lub xeev nyob ruaj khov, piv txwv li, lub sijhawm ywj pheej SE. Lawv suav hais tias tsuas yog cov molecules ruaj khov (cov uas muaj kev teeb tsa uas lub zog ntawm lub nuclei ploj mus) thiab cuam tshuam me me - kev hloov pauv ntawm cov nuclei los ntawm qhov sib npaug.
