Headline news:
Polarization-sensitive ultrafast infrared measurements
on photoinduced electron transfer in donor-acceptor pairs
provide direct access to structure and dynamics of distinctly
different tight and loose ion pairs. |
Link to original paper |
| |
One sentence summary:
Highly anisotropic signals from tight donor-acceptor ion pairs
generated by photoinduced bimolecular electron transfer reveal
the importance of mutual orientation of the reactants and
thus the need to refine theoretical models based on spherical
species that solely involve reaction distances. |

One sentence summary:
Polarization-sensitive ultrafast infrared pump-probe spectroscopy
of DNA oligomer films at well-defined relative humidity provides
insight into the vibrational couplings of N-H and O-H stretching
excitations of adenine-thymine base pairs and water, respectively.

Hunt at University of Strathclyde, Pickett at University of
East Anglia and of Nibbering at the MBI investigate with ultrafast
infrared spectroscopy a model system for active site of [Fe-Fe]-hydrogenase. |

One sentence summary:
Structural changes upon UV irradiation of (µ-S(CH2)3S)Fe2(CO)6
in an alkane solution leads to the formation of two isomers
of the 16-electron complex (µ-S(CH2)3S)Fe2(CO)5
within 50 ps with evidence of a weakly associated solvent
adduct complex. |

Headline news:
Temperature dependence of OH stretching spectral diffusion
in neat liquid water indicate delocalised vibrational excitations
subject to local hydrogen bond network dependent memory loss
of structure. |
Link to original paper |
| |
One sentence summary:
Structural memory loss of water, as evidenced in temperature-dependent
two-dimensional infrared spectra, slows down with decreasing
temperature, beyond vibrational energy transfer times suggesting
delocalization of OH stretching excitations over several water
molecules. |
