Lub sij hawm molar extinction coefficient (ε) yog ib qho kev ntsuas ntawm cov tshuaj muaj zog npaum li cas los yog cov tshuaj absorbs lub teeb ntawm ib qho wavelength. … Cov molar extinction coefficient feem ntau yog siv hauv spectroscopy los ntsuas qhov concentration ntawm cov tshuaj hauv cov tshuaj.
Vim li cas qhov extinction coefficient tas li?
Npias Txoj Cai hais tias molar absorptivity yog tas mus li(thiab qhov absorbance yog proportional to concentration) rau cov khoom muab yaj nyob rau hauv ib tug muab solute thiab ntsuas ntawm ib tug muab wavelength. 2 Vim li no, molar absorptivities hu ua molar absorption coefficients lossis molar extinction coefficients.
Dab tsi cuam tshuam rau molar extinction coefficient?
Peb yam muaj xws li: Tus nqi ntawm lub teeb absorbed los ntawm cov khoom rau ib lub wavelength tshwj xeeb . Txoj kev deb uas lub teeb mus los ntawm kev daws teeb meem . Qhov concentration ntawm cov tshuaj absorbing ib chav tsev ntim.
Puas molar absorption coefficient tas li?
Molar absorption coefficient (ε)
Raws li cov xwm txheej ntawm cov kuab tshuaj, pH thiab qhov kub thiab txias cov molar absorption coefficient rau ib qho kev sib xyaw yog ib qho tas li ntawm qhov teev wavelength"
Puas molar extinction coefficient additive?
Tus nqus coefficient, tseem hu ua extinction coefficient (ε), tuaj yeem tsim los rau txhua qhov muab protein. RauTxhua cov protein los yog peptide, qhov extinction coefficient tuaj yeem txiav txim siab los yog xam los ntawm cov amino acid sib lawv liag, raws li qhov tseeb tias qhov nqus ntawm cov amino acids yog additive.
