FTIR spectroscopy yog siv tau sai thiab meej txheeb xyuas cov tebchaw xws li cov khoom sib xyaw ua ke, cov khoom sib xyaw, muab tshuaj, xim, roj hmab, txheej, cov resins, thiab cov nplaumNws tuaj yeem siv tau thoob plaws txhua qhov. cov theem ntawm cov khoom lifecycle suav nrog kev tsim, tsim khoom, thiab tsis ua haujlwm tsom xam.
Vim li cas peb thiaj siv FTIR spectrophotometer rau feem ntau cov organic tebchaw?
FTIR yog cov txheej txheem spectroscopic raws li ntawm kev nqus ntawm infrared photons uas ua rau muaj kev vibrations ntawm molecular bonds. … Vim tias cov ntiv tes ntawm ntau cov organic tebchaw yog qhov tshwj xeeb, FTIR feem ntau yog siv los muab kev txheeb xyuas qhov zoo.
Cov ntaub ntawv dab tsi tuaj yeem FTIR muab tau?
FTIR yog txoj hauv kev sai, tsis muaj kev puas tsuaj, txuag lub sijhawm uas tuaj yeem ntes ntau pawg ua haujlwm thiab nkag siab rau cov kev hloov pauv hauv cov qauv molecular. FTIR muab cov ntaub ntawv raws li cov tshuaj muaj pes tsawg leeg thiab lub cev lub cev ntawm tag nrho cov qauv (Cocchi li al. 2004).
FTIR siv tau li cas hauv koj qhov kev tshawb fawb?
Fourier transform infrared (FTIR) spectroscopy tshwj xeeb yog siv tau rau kev saib xyuas online ntawm cov khoom siv polymerNws muaj peev xwm ua cov tshuaj ntiv tes ntiv tes tso cai rau FTIR los txiav txim siab cov txheej txheem tshuaj. Nws tau raug siv rau kev tsom xam cov khoom, kua, thiab cov txheej txheem gaseous.

Vim li cas wavenumber siv hauv ir spectroscopy?
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 cov neeg siv khoom thiab cov khoom siv tau siv hauv c ++?
Lub hom phiaj ntawm kev siv getters thiab setters yog txhawm rau zais cov ntaub ntawv khaws cia thiab rov qab li casTxoj kev no, yog tias koj hloov tus cwj pwm, koj tsis tas yuav hloov tus lej. nyob rau hauv ib txhiab qhov chaw. Tab sis, yog tias koj tsis tas yuav hloov qhov kev siv, koj tau ua koj cov cai ntau dua thiab tau txais me ntsis los ntawm kev ua li ntawd .
Vim li cas ir spectroscopy hu ua vibrational spectroscopy?
Ib lub molecule tuaj yeem co ntau txoj hauv kev, thiab txhua txoj hauv kev hu ua hom vibrational. … Unsymmetrical diatomic molecules, e.g. CO, nqus hauv IR spectrum. Ntau cov molecules complex muaj ntau daim ntawv cog lus, thiab lawv cov vibrational spectra yog sib txuas ntau dua, piv txwv li cov molecules loj muaj ntau lub ncov hauv lawv IR spectra .
Vim li cas ftir siv?
FTIR tsom xam yog siv los: Qhia thiab cim cov ntaub ntawv tsis paub (piv txwv li, zaj duab xis, khib nyiab, hmoov, los yog kua) Txheeb xyuas qhov paug ntawm lossis hauv cov khoom (piv txwv li, particles, fibers, hmoov, los yog kua) … txheeb xyuas oxidation, decomposition, los yog uncured monomers nyob rau hauv tsis ua hauj lwm soj ntsuam xyuas .
Txoj cai beer-lambert siv li cas hauv spectroscopy?
Txoj cai BL yog siv ntau txoj hauv kev hauv spectroscopy, tab sis tej zaum qhov kev siv ntau tshaj plaws yog nyob rau hauv txiav txim siab qhov concentration ntawm cov tshuaj ntsuam xyuas hauv cov tshuaj Txoj cai qhia peb tias qhov nqus tau yog sib npaug rau cov concentration zaus ntawm txoj kev ntev lub sij hawm extinction coefficient .
