Time-resolved IR spectroscopy of a trinuclear palladium complex in solution

Unravelling the ultrafast photodecomposition mechanism of dibenzoyl peroxide in solution by time-resolved IR spectroscopy.

The ultrafast photo-fragmentation of dibenzoyl peroxide (DBPO) is studied using femtosecond UV excitation at 266 nm and mid-infrared broadband probe pulses to elucidate the dissociation mechanism. With the help of (13)C-labeled DBPO it was possible to unambiguously assign transient IR bands in the fingerprint region to the benzoyloxy radical. Our experiments show that the fragmentation is contr...

Time-resolved methods in biophysics. 10. Time-resolved FT-IR difference spectroscopy and the application to membrane proteins.

The introduction of time-resolved Fourier transform infrared (FT-IR) spectroscopy to biochemistry opened the possibility of monitoring the catalytic mechanism of proteins along their reaction pathways. The infrared approach is very fruitful, particularly in the application to membrane proteins where NMR and X-ray crystallography are challenged by the size and protein hydrophobicity, as well as ...

Time-resolved fluorescence spectroscopy

Time-resolved IR studies of monolayer self-assembly on a gold substrate using planar array infrared (PA-IR) spectroscopy.

Time-resolved and spatially resolved infrared spectra (line images) of self-assembled monolayers of octadecylthiol (ODT) on gold substrates were investigated by planar array infrared (PA-IR) spectroscopy, with a grazing incidence reflection attachment. It was observed that PA-IR spectra with a good signal-to-noise ratio that is comparable to those obtained from Fourier transform infrared spectr...
