Nonresonant and resonant mode-specific intermolecular vibrational energy transfers in electrolyte aqueous solutions.
The donor/acceptor energy mismatch and vibrational coupling strength dependences of interionic vibrational energy transfer kinetics in electrolyte aqueous solutions were investigated with ultrafast multiple-dimensional vibrational spectroscopy. An analytical equation derived from the Fermi's Golden rule that correlates molecular structural parameters and vibrational energy transfer kinetics was...
متن کاملMode-specific intermolecular vibrational energy transfer. I. Phenyl selenocyanate and deuterated chloroform mixture
Vibrational energy transfer from the first excited state 2252 cm−1 of the C–D stretch of deuterated chloroform DCCl3 to the 0-1 transition 2155 cm−1 of the CN stretch of phenyl selenocyanate C6H5SeCN in their 1:1 liquid mixture was observed with a pump/probe two-color two dimensional infrared spectroscopic technique. The mode-specific energy transfer can occur mainly because of the long vibrati...
متن کاملMode-specific intermolecular vibrational energy transfer. II. Deuterated water and potassium selenocyanate mixture.
Vibrational energy transfer from the first excited state (2635 cm(-1)) of the O-D stretch of deuterated water (D(2)O) to the 0-1 transition (2075 cm(-1)) of the CN stretch of potassium selenocyanate (KSeCN) in their 2.5:1 liquid mixture was observed with a multiple-mode two dimensional infrared spectroscopic technique. Despite the big energy mismatch (560 cm(-1)) between the two modes, the tran...
متن کاملIntermolecular vibrational energy transfers in liquids and solids.
Resonant and nonresonant intermolecular vibrational energy transfers in KSCN/KSC(13)N/KS(13)C(15)N aqueous and DMF solutions and crystals are studied. Both energy-gap and temperature dependent measurements reveal some surprising results, e.g. inverted energy-gap dependent energy transfer rates and opposite temperature dependences of resonant and nonresonant energy transfer rates. Two competing ...
متن کاملUltrafast intermolecular energy transfer in heavy water.
We report on a study of the vibrational energy relaxation and resonant vibrational (Förster) energy transfer of the OD vibrations of D2O and mixtures of D2O and H2O using femtosecond mid-infrared spectroscopy. We observe the lifetime of the OD vibrations of bulk D2O to be 400 +/- 30 fs. The rate of the Förster energy transfer is measured via the dynamics of the anisotropy of the OD vibrational ...
