7 November 2016

Headline news:
A research team of scientists from the MBI and Martin-Luther-Universität Halle-Wittenberg explore the first electronic excited state of 7-hydroxyquinoline to assess its photoacid and photobase behaviour.


Link to original paper

 

One sentence summary:
A combined ultrafast IR pump-probe study anddensity functional study enables the characterization of the four charged forms of 7-hydroxyquinoline, to determine the excited state charge redistribution and its role in photoinduced proton transfer pathways.

Headline news:
A research team of scientists from the MBI determine with femtosecond 2D-IR spectroscopy the ultrastrong, ultrafast and local nature of electric fields by hydration shell water at the surface of DNA.


Link to original paper

 

One sentence summary:
New experiments in the ultrafast time domain show that the first two water layers at the DNA surface generate electric fields of up to 100 megavolts/cm which fluctuate on the femtosecond time scale and are limited to a spatial range on the order of 1 nm.

4 July 2016

Headline news:
A research team of scientists from the MBI and the Ben Gurion University of the Negev show that the ultrabroad infrared absorption of hydrated protons reflects the fluctuating surrounding liquid structure, steering the hydrated proton on ultrafast time scales.


Link to original paper

 

One sentence summary:
By dissecting the infrared broadband absorption from OH stretching and bending transitions with femtosecond IR pump-probe spectroscopy, it is shown that the continuum for the Zundel cation H5O2+ is due to ultrafast modulated transition of the proton transfer mode, augmented with thermal excitations of low-frequency modes.
