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

One sentence summary:
The key role of hydration for mediating ultrafast energy migration
and dissipation in phospholipids self-assembled into reverse
micelles is exemplified by determination of the rate of resonant
excitation transfer between phosphate groups and by introducing
a water pool as a confined heat sink for excess energy. |

Headline news:
In a collaboration between the Nibbering (MBI) and Batista
(Yale University, USA) teams the solvent-induced OH stretching
frequency shifts of a prototypical photoacid dissolved in
nonpolar/weakly polar solvents are explained in a combined
transient IR spectroscopic and quantum chemical calculational
study. |

One sentence summary:
The vibrational frequency shifts of the OH-stretching mode
of uncomplexed 2-naphthol observed with femtosecond IR spectrosocpy
in the electronic ground and excited states are explained
using a perturbative solute-solvent interaction model and
parametrized by (TD-)DFT quantum chemcial calculations. |
