- ItemUltrafast proton coupled electron transfer (PCET) dynamics in 9-anthranol-aliphatic amine system(Les Ulis : EDP Sciences, 2013) Ghosh, H.N.; Adamczyk, K.; Verma, S.; Dreyer, J.; Nibbering, E.T.J.Femtosecond infrared absorption studies strongly suggest that photoexcited 9-anthranol takes part in an ultrafast electron transfer (ET) reaction in electron-donating triethylamine solvent, but that ultrafast proton coupled electron transfer (PCET) occurs in diethylamine solvent.
- ItemUltrafast OH-stretching frequency shifts of hydrogen-bonded 2-naphthol photoacid-base complexes in solution(Les Ulis : EDP Sciences, 2013) Prémont-Schwarz, M.; Xiao, D.; Sekharan, S.; Batista, V.S.; Nibbering, E.T.J.We characterize the transient solvent-dependent OH-stretching frequency shifts of photoacid 2-naphthol hydrogen-bonded with CH3CN in the S0- and S1-states using a combined experimental and theoretical approach, and disentangle specific hydrogen-bonding contributions from nonspecific dielectric response.
- ItemUltrafast IR pump-probe and 2D-IR photon echo spectroscopy of adenosine-thymidine base pairs(Les Ulis : EDP Sciences, 2013) Greve, C.; Preketes, N.K.; Costard, R.; Koeppe, B.; Fidder, H.; Nibbering, E.T.J.; Temps, F.; Mukamel, S.; Elsaesser, T.We characterize diagonal and off-diagonal anharmonicities of N-H stretching vibrations in adenosine and thymidine monomers and in A•T-base pairs in chloroform solution, showing the important role of coupling between vibrationally excited N-H stretching states.
