Triply vibrationally enhanced plaub-yoj sib xyaw spectroscopy yog ua hauj lwm los soj ntsuam kev coherence hloov ntawm asymmetric thiab symmetric CO-stretching hom ntawm rhodium (I) dicarbonyl acetylacetonate (RDC).Coherence hloov pauv yog ib qho kev hloov pauv tsis zoo ntawm kev sib koom ua ke ntawm quantum xeev mus rau qhov sib txawv coherent superposition vim kev sib txuas ntawm cov qauv vibrational los ntawm da dej.Tag nrho peb qhov kev zoo siab pulses nyob rau hauv qhov kev sim yog resonant nrog ib tug tib quantum coherence, tab sis coherence hloov mus rau hauv tshiab coherences nrog txawv frequencies.Tus tshiab tso zis zaus yog pom nrog ib tug monochromator uas daws nws los ntawm qhov muaj zog ncov ntawm thawj excitation zaus.Cov txheej txheem no spectrally daws txoj hauv kev uas suav nrog kev sib hloov pauv, kev ntxub ntxaug tawm tsam cov yam ntxwv tsim los ntawm kev hloov pauv hluav taws xob nkaus xwb, thiab daws cov kev hloov pauv mus ib ntus uas tsim los ntawm kev cuam tshuam ntawm kev sib txawv ntawm txoj hauv kev sib txawv.Redfield txoj kev xav simu lates cov kev hloov ntawm lub cev nyob rau hauv lub impulsive txwv, tab sis nws kuj yog tseeb hais tias coherence hloov mus ua txhaum lub secular approximation invoked nyob rau hauv feem ntau Redfield txoj kev xav.Xwb, nws yuav tsum tsis-Markovian thiab da dej nco los.RDC tuaj yeem muab tus qauv yooj yim rau kev txhim kho cov kev xav uas suav nrog cov teebmeem no.
