Molecular origin of 31P-NMR chemical shifts of phosphate groups with bivalent counter ions
Leo Christanell, Karl-Jakob König, Julian Holzinger +2
The electrostatic interactions of phosphate groups and counter ions critically affect the structure, function and reactivity of DNA or RNA. We present a joint experimental-theoreti…
Field-Induced Electron Generation in Water: Solvation Dynamics and Many-Body Interactions
Michael Woerner, Benjamin P. Fingerhut, Thomas Elsaesser
The solvated electron represents an elementary quantum system in a liquid environment. Electrons solvated in water have raised strong interest because of their prototypical propert…
Structural Discrimination of Phosphate Contact Ion Pairs in Water by Femtosecond 2D-IR Spectroscopy
Achintya Kundu, Jakob Schauss, Benjamin P. Fingerhut +1
The distinct structures of contact ion pairs in water are identified. Nonlinear infrared (IR) spectroscopy and theoretical calculations allow for the separation and assignment of s…
Impact of RNA Melting on Hydrating Water Structure Mapped by Femtosecond 2D-IR Spectroscopy
Benjamin P. Fingerhut, Achintya Kundu, Jakob Schauss +1
We discern hydration geometries around the sugar-phosphate-backbone of an RNA double helix at the molecular level. RNA disordering upon melting is connected with a transition from…
Phosphate Vibrations Probe Electric Fields in Hydrated Biomolecules: Spectroscopy, Dynamics, and Interactions
Thomas Elsaesser, Jakob Schauss, Achintya Kundu +1
Electric interactions have a strong impact on the structure and dynamics of biomolecules in their native water environment. Given the variety of water arrangements in hydration she…
Terahertz Polaron Oscillations of Electrons Solvated in Liquid Water
Ahmed Ghalgaoui, Benjamin P. Fingerhut, Klaus Reimann +2
The terahertz (THz) response of solvated electrons in liquid water is studied in nonlinear ultrafast pump-probe experiments. Free electrons with concentrations from c_e = 4 to 140…
