15 August 2017

Headline news:
A joint experimental and theoretical study by scientists from the MBI, HZB-BESSYII, Stockholm University, the University of Zurich and Magnosco GmbH, shows how to grasp the hydrogen bonding effects on the vibrational and electronic structure of ammonia and ammonium ion in aqueous solution.

One sentence summary:
FT-IR and soft-x-ray spectroscopy provide two local probes to characterize hydrogen bonding properties of aqueous NH3 and NH4+ with which it can be shown that, despite a clear difference in the number of hydrogen bonds, an intimate relationship exists in the electronic structure of the two key amine compounds.

Headline news:
A research team of scientists from the MBI and the Ben Gurion University of the Negev map fluctuating proton transfer motions of protons shared by two water molecules by directly monitoring the proton transfer mode with ultrafast infrared spectroscopy.

One sentence summary:
Protons in liquid water are predominantly shared by two water molecules with femtosecond proton elongations within a hydration site 10 to 50 times faster than proton hopping to a new site, the elementary proton transfer step in chemistry.
