Wavenumber yog yooj yim heev vim nws tseem tso cai rau IR spectrum muab piv thiab tseem yog qhov ntsuas ntawm lub zog. … Spectroscopists nyiam siv wavenumber (hauv K, 1K=cm-1) hauv FTIR thiab Raman spectroscopies vim nws scales linearly nrog lub zog.
Vim li cas yoj tus lej siv hauv IR spectroscopy es tsis yog wavelength?
Kev xaiv siv wavenumbers rau infrared spectroscopy (xws li wavelengths, frequencies, los yog energies) yog tej zaum ua tiav muab qhov ntau yam uas muaj ob qho tib si ntawm qhov dav (kom qhov sib txawv ntawm ob lub ncov yog lub ntsiab lus ntau dua) thiab nthuav cov txheej txheem tsim nyog uas tsis muaj qhov loj lossis ntau heev…
Yuav ua li cas yog tus nab npawb hauv IR spectroscopy?
A wavenumber is the reciprocal of a wavelength (1/λ) ; Yog li, tus lej ntawm 1600 cm-1 sib raug rau lub wavelength ntawm. 11600 cm² - 1=6.25 × 10 - 4 cm los yog 6.25 μ m. Organic chemists pom nws yooj yim dua los cuam tshuam nrog wavenumbers es tsis yog wavelengths thaum tham txog infrared spectra.
tus nab npawb siv rau dab tsi?
Wavenumber, tseem hu ua yoj tus lej, ib chav ntawm zaus, feem ntau siv hauv atomic, molecular, thiab nuclear spectroscopy, sib npaug rau qhov tseeb zaus faib los ntawm kev ceev ntawm nthwv dej thiab yog li sib npaug rau cov nthwv dej hauv ib chav nyob deb.
yoj tus lej hauv spectroscopy yog dab tsi?
Hauv kev tshawb fawb lub cev, tus lej wavenumber (kuj yoj tus lej lossis rov ua dua) yog qhov ntau zaus ntawm nthwv dej, ntsuas hauv ib lub voj voog ib chav nyob deb lossis radians ib chav nyob deb. Thaum lub sijhawm ntuav tuaj yeem xav tias yog tus naj npawb ntawm nthwv dej ntawm ib lub sijhawm, wavenumber yog tus naj npawb ntawm nthwv dej ntawm ib chav nyob.
