? Ib qho tseem ceeb Qhov zoo ntawm Raman spectra tshaj infrared nyob rau hauv qhov tseeb hais tias dej tsis ua 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).

Yog li ntawd, qhov zoo ntawm Raman spectroscopy yog dab tsi?

Qhov zoo ntawm Raman Spectroscopy tsis cuam tshuam los ntawm dej. tsis muaj kev puas tsuaj. tshwj xeeb heev zoo li cov tshuaj ntiv tes ntawm cov khoom. Raman spectra tau txais sai sai hauv vib nas this.

Tsis tas li ntawd, vim li cas dej thiaj siv tau los ua cov kuab tshuaj hauv Raman Spectroscopy? Dej ua tsis tau siv nyob rau hauv IR vim nws mob siab heev nqus ntawm IR, whereas nws tuaj yeem siv los ua cov kuab tshuaj hauv Raman spectroscopy . Qhov tseeb tias dej yog ib tug qaug zog Raman scatterer txhais tau tias cov qauv ua tau muab tshuaj ntsuam xyuas hauv lawv daim ntawv aqueous, uas muaj txiaj ntsig zoo rau kev lag luam kws tshuaj.

Tsis tas li ntawd, qhov txawv ntawm Raman thiab IR spectroscopy yog dab tsi?

Raman spectra tshwm sim los ntawm tawg ntawm lub teeb los ntawm vibrating molecules whereas IR spectra tshwm sim los ntawm lub teeb nqus los ntawm vibrating molecules. Raman Kev ua haujlwm tshwm sim los ntawm kev hloov pauv ntawm polarizability ntawm ib qho molecule whereas IR kev ua tau los ntawm kev hloov lub sijhawm dipole. Raman cov txheej txheem tsis yog kev puas tsuaj.

Vim li cas laser siv hauv Raman Spectroscopy?

Raman Spectroscopy . Lub teeb qhov chaw siv nyob rau hauv Raman spectroscopy yog a laser . Cov laser teeb yog siv vim hais tias nws yog ib lub teeb hnyav heev ntawm ze li ntawm lub teeb monochromatic uas tuaj yeem cuam tshuam nrog cov qauv molecules. Thaum teeb meem absorbs lub teeb, lub zog sab hauv ntawm qhov teeb meem yog hloov nyob rau hauv qee txoj kev.
