Bathochromic hloov pauv: Hauv spectroscopy, txoj haujlwm hloov ntawm lub ncov lossis lub teeb liab mus ntev wavelength (qis zog). Kuj hu ua kev hloov pauv liab.
Lub ntsiab lus ntawm kev hloov pauv da dej yog dab tsi?
Bathochromic hloov (los ntawm Greek βαθύς bathys, "sib sib zog nqus"; thiab χρῶμα chrōma, "xim"; yog li tsis tshua muaj kev sib hloov "bathychromic") yog kev hloov ntawm spectral band txoj hauj lwm hauv kev nqus, reflectance, transmittance, los yog emission spectrum ntawm ib tug molecule mus rau ib tug ntev wavelength (tsawg zaus)
Vim li cas thiaj ua rau da dej ua haujlwm?
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. … Qhov kev siv zog ntawm kev nqus (εmax) kuj nce nrog qhov nce ntawm qhov ntev ntawm chromophore.
Dab tsi yog qhov txawv ntawm kev hloov pauv ntawm da dej thiab hypsochromic hloov?
Bathochromic: kev hloov ntawm ib pawg kom qis zog lossis ntev wavelength (feem ntau hu ua hloov pauv liab). Hypsochromic: kev hloov ntawm ib pawg mus rau lub zog siab dua lossis luv dua wavelength (feem ntau hu ua kev hloov xim xiav).
bathochromic hloov pauv cuam tshuam li cas rau kev sib txuas?
Qhov muaj qhov sib txuas hauv cov molecule ib txwm ua rau kev hloov pauv ntawm da dej. Qhov loj dua qhov kev sib txuas ntau dua yuav yog da dej chromic hloov. Lub xub ntiag ntawm conjugation yog lub luag hauj lwm tsis tsuas yog rau qhov nce nyob rau hauv lub nqus wavelength, tab sis kuj rau qhov nce nyob rau hauv kev siv ntawm absorption.
