Qhov sib txawv tseem ceeb ntawm kev hloov pauv ntawm da dej thiab hypsochromic hloov pauv yog qhov hloov pauv ntawm da dej yog qhov hloov pauv ntev dua, qhov kev hloov pauv hypsochromic yog qhov luv dua wavelength hloov.
Bathochromic hloov pauv tuaj yeem piav qhia raws li kev hloov pauv ntawm spectral band txoj haujlwm hauv kev nqus, kev cuam tshuam, kev xa tawm, lossis emission spectrum ntawm cov molecule mus rau lub wavelength ntev. Kev hloov pauv hypsochromic tuaj yeem piav qhia raws li kev hloov pauv ntawm spectral band txoj haujlwm hauv kev nqus, kev xav, kev xa tawm, lossis emission spectrum ntawm cov molecule uas raug rau lub wavelength luv dua.
Bathochromic Shift yog dab tsi?
Bathochromic hloov pauv tuaj yeem piav qhia raws li kev hloov pauv ntawm spectral band txoj haujlwm hauv kev nqus, kev cuam tshuam, kev xa tawm, lossis emission spectrum ntawm cov molecule mus rau lub wavelength ntev. Txij li cov xim liab nyob rau hauv qhov pom spectrum muaj qhov ntev wavelength, peb tuaj yeem hu cov nyhuv no redshift.
Daim duab 01: Liab ua haujlwm thiab xiav ua haujlwm
Bathochromic hloov pauv tuaj yeem tshwm sim vim muaj kev hloov pauv ntawm ib puag ncig, xws li kev hloov pauv hauv cov kuab tshuaj polarity, uas tuaj yeem ua rau muaj solvatochromism. Tsis tas li ntawd, cov txheej txheem ntawm cov qauv molecules uas tshwm sim hauv kev hloov pauv kuj tuaj yeem tso tawm qhov hloov pauv ntawm da dej. Peb tuaj yeem pom qhov tshwm sim no hauv molecular spectra tab sis tsis nyob hauv atomic spectra. Yog li ntawd, nws yog qhov ntau dua thaum xav txog kev txav ntawm lub ncov hauv cov spectrum ntau dua li cov kab. Peb tuaj yeem tshawb pom qhov hloov pauv ntawm da dej tau yooj yim nrog kev siv lub spectrophotometer, colorimeter, thiab spectroradiometer.
Hypsochromic Shift yog dab tsi?
Hypsochromic hloov pauv tuaj yeem piav qhia raws li kev hloov pauv ntawm spectral band txoj haujlwm hauv kev nqus, kev xav, kev xa tawm, lossis emission spectrum ntawm lub molecule uas raug rau luv luv wavelength. Txij li thaum pom spectrum qhia tau hais tias luv luv wavelength rau cov xim xiav, peb tuaj yeem hu qhov kev hloov pauv xiav no.
Hypsochormic hloov tuaj yeem tshwm sim vim muaj kev hloov pauv hauv ib puag ncig, xws li kev hloov pauv hauv cov kuab tshuaj polarity uas tuaj yeem ua rau solvatochromism. Tsis tas li ntawd, cov txheej txheem ntawm cov qauv molecules uas tshwm sim nyob rau hauv ib qho kev hloov pauv tuaj yeem ua rau pom kev hloov hypsochromic. Peb tuaj yeem pom qhov tshwm sim no hauv molecular spectra tab sis tsis nyob hauv atomic spectra. Yog li ntawd, nws yog qhov ntau dua thaum xav txog kev txav ntawm lub ncov hauv cov spectrum ntau dua li cov kab. E.g. beta-acylpyrrole tuaj yeem pom qhov hloov pauv hypsochromic ntawm 30-40 nm thaum piv nrog alpha-acypyrroles.
Qhov txawv ntawm Bathochromic Shift thiab Hypsochromic Shift yog dab tsi?
Bathochromic hloov thiab hypsochromic hloov yog cov ntsiab lus tseem ceeb analytical. Qhov sib txawv tseem ceeb ntawm kev hloov pauv ntawm tus da dej thiab hypsochromic hloov pauv yog qhov hloov pauv ntawm tus da dej yog qhov hloov pauv ntev dua, qhov kev hloov pauv hypsochromic yog qhov luv dua wavelength hloov. Bathochromic hloov yog hu ua redshift, thaum hypsochromic hloov yog hu ua xiav hloov. Ntxiv mus, kev hloov pauv ntawm da dej muaj qhov tsawg dua thaum lub hypsochromic hloov pauv muaj ntau zaus.
Cov hauv qab no qhia txog qhov sib txawv ntawm kev hloov pauv ntawm da dej thiab hypsochromic hloov pauv hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Bathochromic Shift vs Hypsochromic Shift
Bathochromic hloov pauv tuaj yeem piav qhia raws li kev hloov pauv ntawm spectral band txoj haujlwm hauv kev nqus, kev cuam tshuam, kev xa tawm, lossis emission spectrum ntawm cov molecule mus rau lub wavelength ntev. Kev hloov hypsochromic tuaj yeem piav qhia raws li kev hloov pauv ntawm spectral band txoj haujlwm hauv kev nqus, kev xav, kev xa tawm, lossis emission spectrum ntawm cov molecule uas raug rau luv luv wavelength. Qhov sib txawv tseem ceeb ntawm kev hloov pauv ntawm da dej thiab hypsochromic hloov pauv yog qhov hloov pauv ntawm da dej yog qhov hloov pauv ntev dua, qhov kev hloov pauv hypsochromic yog qhov luv luv wavelength hloov.
