Hypochromic effect Bathochromic hloov / cuam tshuam (Liab hloov): Nws yog ib qho txiaj ntsig vim qhov kev nqus siab tshaj plaws tau hloov mus rau qhov ntev wavelength rau qhov muaj auxochrome lossis los ntawm kev hloov pauv ntawm polarity ntawm hnyav. … Tsis tas li ntawd xwb, muaj cov pab pawg alkyl ntawm ob daim ntawv cog lus ua rau kev hloov pauv ntawm da dej.
Vim li cas thiaj ua rau da dej ua haujlwm?
Nws tuaj yeem tshwm sim vim ntawm kev hloov pauv hauv ib puag ncig: piv txwv li, kev hloov pauv ntawm cov kuab tshuaj polarity yuav ua rau solvatochromism. Cov txheej txheem ntawm cov qauv molecules nyob rau hauv ib qho kev hloov pauv kuj tseem tuaj yeem qhia txog kev hloov pauv ntawm da dej.
Yuav ua li cas thaum da dej ua haujlwm?
BATHOCHOMIC SHIFT. Kev hloov pauv ntawm kev nqus mus rau lub sijhawm ntev dua vim yog hloov pauv lossis hnyav hnyav(kev hloov pauv liab). … Kev hloov pauv ntawm kev nqus mus rau lub wavelength luv dua vim yog hloov pauv lossis hnyav hnyav (hloov pauv xiav).
Dab tsi yog kev hloov pauv ntawm da dej piav qhia nrog piv txwv?
Bathochromic hloov: Hauv spectroscopy, txoj haujlwm hloov ntawm lub ncov lossis lub teeb liab mus rau lub wavelength ntev (qis zog) Kuj hu ua hloov pauv liab. … Rau qhov siab tshaj qhov nqus pib ntawm λmax=550 nm, hloov mus rau siab dua wavelength xws li 650 nm yog da dej, qhov hloov mus rau qis dua wavelength xws li 450 nm yog hypsochromic.
Hypsochromic hloov pauv txhais li cas?
Hypsochromic hloov pauv (los ntawm Greek thaum ub ὕψος (upsos) "qhov siab"; thiab χρῶμα chrōma, "xim") yog kev hloov pauv ntawm spectral band txoj hauj lwm hauv kev nqus, kev xav, kev xa tawm, lossis emission spectrum ntawm ib tug molecule mus rau ib tug luv luv wavelength (ntau zaus)
