Ntawm qhov tod tes, heteromuclear diatomic molecules zoo li HCI, CO, TSIS MUAJ thiab lwm yam . thiab polyatomic molecules zoo li CO2, H2O, CH4 thiab lwm yam. uas qhia txog kev hloov pauv ntawm lub sijhawm dipole hauv qee hom kev co spectra thiab yog hais tias yog infrared-active.
Lub molecule twg tsis muab kev vibrational spectra?
Teb: homonuclear diatomic molecule zoo li H2, O2, N2 thiab lwm yam. uas tsuas muaj zog ncab / vibrations thiab tsis muaj dabtsi yog khoov / vibrations, lub dipole lub sij hawm tsis hloov thaum vibration. Yog li cov molecules no tsis muab kev vibration spectra piv txwv li lawv tau hais tias yog infrared-infrared
hom molecules dab tsi nthuav tawm kev vibrational rotational spectra thiab vim li cas?
Kev piav qhia: Hf qhia kev sib hloov thiab lossis kev vibrational spectra. Qhov no yog vim tsis zoo li cov molecules ntawm, CO thiab NO; Hf tsis yog linear molecule. Lub rotational spectra sib haum rau lub zog ntawm microwave hluav taws xob.
Qhov twg hauv qab no yog piv txwv ntawm kev vibrational spectroscopy?
Vibrational spectroscopy suav nrog ntau cov tswv yim, tab sis qhov tseem ceeb tshaj plaws yog mid-infrared (MIR), ze-IR (NIR), thiab Raman spectroscopy. Ob leeg MIR thiab Raman spectroscopy muab cov yam ntxwv tseem ceeb vibrations uas yog siv rau elucidation ntawm molecular qauv.
Nyob hauv cheeb tsam twg yog vibrational spectra tau txais?
Infrared spectroscopy (IR spectroscopy lossis Vibrational Spectroscopy) yog spectroscopy uas cuam tshuam nrog thaj tsam infrared ntawm electromagnetic spectrum, uas yog lub teeb nrog lub wavelength ntev thiab qis dua li pom. teeb.
Pom zoo:
Puas yog kev cob qhia lossis kev cob qhia?
Thiab ntawm no yog qhov kuv pom: yog, nws yog qhov siv tau los siv ntau daim ntawv "kev cob qhia"Tab sis tsuas yog hauv Asmeskas Lus Askiv thiab tsuas yog thaum hais txog kev cob qhia kev cob qhia raws li tus kheej. Cov phau ntawv txhais lus Askiv zoo tshaj plaws hauv Asmeskas, Merriam-Webster, pom zoo tias ntau qhov kev cob qhia yog "
Vim li cas cov neeg nthuav qhia siv cov kev pab nthuav qhia?
Presentation aids pab cov neeg mloog kom nkag siab ntau ntxiv txog tus neeg hais lus ua ob txoj hauv kev: lawv pab qhia meej thiab lawv pab qhia. Cov kev pab nthuav qhia tuaj yeem pab cov neeg tuaj saib kom nkag siab txog cov tswv yim nyuaj lossis cov txheej txheem thiab tseem tuaj yeem qhia tias cov tswv yim twg tseem ceeb tshaj plaws hauv kev hais lus .
Leej twg qhia cov lus qhuab qhia ntawm kev koom tes koom nrog?
Kev Sib Koom Tes Sib Koom Tes yog thawj zaug los ntawm Fabkis East India Tuam Txhab Tus Thawj Kav Tebchaws Joseph Francois Dupleix Nws tau siv tom qab ntawd los ntawm Lord Wellesley uas yog Tus Thawj Kav Tebchaws ntawm Is Nrias teb los ntawm 1798 txog 1805 Thaum ntxov ntawm nws txoj kev tswj hwm, Tswv Wellesley tau txais txoj cai tsis muaj kev cuam tshuam hauv cov thawj tswj hwm .
Cov kev qhuab qhia twg yog qhov kev xav txog kev xav ntawm cov niam txiv kev txawj ntse?
Psychology cov niam txiv kev txawj ntse yog cov kev qhuab qhia ntawm philosophy thiab physiology. Ib qho kev tshawb fawb tshiab tau yug los vim tias Philosophers thiab physiologists tau xav txog seb lub siab thiab lub cev cuam tshuam li cas.
Puas kev qhia qhia suav nrog kev qhia?
Yog, nws ua Puas kev qhia ntawv suav nrog kev ua haujlwm? Yog, kev qhia ntawv, txawm tias koj tau ua nws ntiag tug lossis los ntawm lub tuam txhab qhia ntawv yog "ua haujlwm." Yog li koj yog tus nqi kom suav nrog nws hauv koj qhov kev xav tau.
