Infrared spectroscopy yog siv rau hauv kev tshawb fawb los txheeb xyuas cov qauv, ua quantitative analysis, los yog ntes impurities . Infrared spectroscopy tuaj yeem siv rau ntawm gaseous, kua, los yog khoom kuaj thiab ua tsis rhuav tshem cov qauv hauv cov txheej txheem.
Yog li ntawd, ua li cas infrared spectroscopy txiav txim siab purity?
Rau lub hom phiaj ntawm kev huv tswj, spectral sib piv yog ua los ntawm regressing lub infrared spectrum ntawm ib qho piv txwv uas muaj feem cuam tshuam rau ntawm kev siv spectrum ntawm cov ntshiab compound. Qhov txiaj ntsig kev sib txheeb coefficient, R, yog a ntsuas ntawm qhov sib xws ntawm ob qho tib si spectrum.
Qhov thib ob, yuav ua li cas txhim khu kev qha infrared spectroscopy? Infrared spectroscopy yog ib qho cuab yeej muaj zog los txiav txim siab cov ntsiab lus tseem ceeb thiab cov yam ntxwv zoo ntawm cov khoom siv mis nyuj. Ntau qhov piv txwv thiab daim ntawv thov qhia tias cov txheej txheem yog qhov tseeb thiab nrawm thiab tuaj yeem siv rau kev tswj cov txheej txheem.
Qhov thib ob, infrared spectroscopy ntsuas dab tsi?
Infrared Spectroscopy yog tus tsom xam ntawm infrared lub teeb interacting nrog ib tug molecule. IR Spectroscopy ntsuas cov kev vibrations ntawm atoms, thiab raws li qhov no nws muaj peev xwm los txiav txim siab lub functional pawg. 5 Feem ntau, cov ntawv cog lus muaj zog thiab lub teeb atoms yuav vibrate ntawm lub siab stretching zaus (wavenumber).
FTIR txawv ntawm infrared spectroscopy li cas?
IR sawv rau ' Infrared ' uas txawv ntawm 2.5µm mus rau 15µm hauv electromagnetic spectrum. FTIR ntawm qhov tod tes yog ib spectroscopic txheej txheem. FTIR yog dav siv vim nws ua tau tsim ib qho interferogram hauv ib pliag. Ib qho interferogram yog ib tug complex qauv uas muaj tag nrho cov infrared zaus.

Dab tsi ntawm impurities tuaj yeem raug tshem tawm ntawm cov organic compound los ntawm distillation?
Ua haujlwm kom raug, distillation tuaj yeem tshem tawm txog 99.5 feem pua ntawm cov impurities ntawm dej, suav nrog cov kab mob, hlau, nitrate, thiab cov khoom tawg
Dab tsi tuaj yeem pom infrared telescopes pom?
Infrared telescopes tuaj yeem kuaj pom cov khoom txias dhau --- thiab yog li ntawd dhau lawm faint --- yuav tsum tau pom nyob rau hauv pom lub teeb, xws li cov ntiaj chaw, ib co nebulae thiab cov hnub qub xim av dwarf. Tsis tas li ntawd, cov hluav taws xob infrared muaj lub wavelengths ntev dua li pom lub teeb, uas txhais tau hais tias nws tuaj yeem dhau los ntawm cov pa roj thiab hmoov av tsis tau tawg
Vim li cas infrared spectroscopy tseem ceeb?
Nws yog siv los ntawm chemists los txiav txim siab ua haujlwm pab pawg hauv cov molecules. IR Spectroscopy ntsuas qhov kev vibrations ntawm atoms, thiab raws li qhov no nws muaj peev xwm txiav txim siab cov pab pawg ua haujlwm. 5 Feem ntau, cov ntawv cog lus muaj zog thiab lub teeb atoms yuav vibrate ntawm lub siab stretching zaus (wavenumber)
Dab tsi yog qhov zoo ntawm Raman spectroscopy tshaj infrared spectroscopy?
Ib qho txiaj ntsig tseem ceeb ntawm Raman spectra tshaj infrared nyob rau hauv qhov tseeb tias dej tsis cuam tshuam, qhov tseeb, Raman spectra tuaj yeem tau txais los ntawm cov kev daws teeb meem aqueous. 12.? Dej tuaj yeem siv los ua cov kuab tshuaj. ? Zoo heev rau cov qauv tshuaj lom neeg hauv lub xeev (vim tias dej tuaj yeem siv los ua hnyav)
Dab tsi tuaj yeem fluorescent hauv situ hybridization ntes tau?
Fluorescent nyob rau hauv situ hybridization (FISH) tuaj yeem siv los ntsuas qhov muaj lossis tsis muaj cov cheeb tsam chromosome thiab feem ntau siv los kuaj xyuas cov chromosome me me xws li Williams syndrome. Qhov no suav nrog kev siv DNA tshwj xeeb sojntsuam uas lees paub thaj av los kuaj
