Headline news:
Researchers of the Max-Born-Institute at Berlin, Germany, have observed how biomolecules transfer energy into extremely small water droplets in their environment. A water shell consisting of only 3 water molecules around a phospholipid molecule is sufficient for energy transfer within 1 ps.

Headline news:
Researchers at the Max Born Institute, the Christian-Albrechts-Universität zu Kiel and the University of california at Irvine show that the interplay of diagonal anharmonic frequency shifts and excitonic coupling results in different spectroscopic behaviour of the fundamental and excited state transitions of the N-H stretching modes of adenosine monomer.


Link to original paper

 

One sentence summary:
In a combined experimental and theoretical nonlinear IR spectroscopic approach, the fundamental and first overtone N-H stretching transitions of adenosine monomer can be fully mapped out, using a description halfway between the normal and the local mode picture.

Headline news:
The role of alkali cations in the solvation of released electrons in aqueous solution at the liquid to vacuum interface has been demonstrated by the observation of a transient (cation...electron) complex.


Link to original paper

 

One sentence summary:
Using VUV pulses shorter than 20 fs tuned at 160 nm, besides solvated electrons with a binding energy of 3.4 eV, a transient hydrated (cation…electron) complex is observed at the surface of the liquid jet with a binding energy of only about 2.5 eV.

Headline news:
In a collaboration between the Elsaesser/Nibbering (MBI) and Levinger (Colorado State University, USA) teams the vibrational dynamics of the water in phospholipid reverse micelles are investigated with ultrafast two-colour mid-IR pump-probe spectroscopy.


Link to original paper

 

One sentence summary:
Spectral diffusion of the OH stretching mode of water confined in phospholipid reverse micelles accelerates with increased size of the water pool, accompanied by an decrease of the OH stretching lifetime, relaxing via the bending mode of water.
