Iimveliso

I-spekkografi yokuxuba amaza amaza kathathu aphuculwe ngokuphindwe kathathu isetyenziselwe ukujonga utshintshiselwano oluhambelanayo lokungcangcazela phakathi kwe-asymmetric kunye ne-symmetric CO-stretching modes yerhodium(I) dicarbonyl acetylacetonate (RDC).Ukutshintshwa kokuhambelanayo kukutshintshwa kwe-nonradiative ye-superposition ehambelanayo ye-quantum states ukuya kwi-superposition eyahlukileyo ehambelanayo ngenxa yokudibanisa iindlela zokungcangcazela ngokusebenzisa ibhafu.Zontathu ii-excitation pulses kuvavanyo zihambelana nokuhambelana kwe-quantum enye, kodwa ukudluliselwa kokubambisana kubangela ukuhambelana okutsha kunye neefrikhwensi ezahlukeneyo.Imveliso entsha frequency ijongwa nge-monochromator eyisombululayo ukusuka kwincopho eyomeleleyo kwi-excitation frequency yasekuqaleni.Obu buchwephesha busombulula ngokubonakalayo iindlela ezibandakanya utshintshiselwano oluhambelanayo, lucalula izinto ezibonakalayo ezidalwe kuphela ziinguqu zemitha, kwaye zisombulula okwethutyana iimodyuli ezidalwe luphazamiseko phakathi kweendlela ezahlukeneyo zotshintshiselwano oluhambelanayo.Ithiyori yeRedfield ilinganisa uhlengahlengiso lwexeshana kumda wokungxamiseka, kodwa kukwacacile ukuba ukuhanjiswa kwentsebenziswano kwaphula uqikelelo lwelizwe olubizwe kwiithiyori ezininzi zeRedfield.Endaweni yoko, ifuna i-non-Markovian kunye neziphumo zememori yokuhlamba.I-RDC inokubonelela ngemodeli elula yophuhliso lweethiyori ezibandakanya ezi ziphumo.
