Femtosecond pump-probe experiments are used to study the photophysics and photochemistry of heme proteins on ultrafast time scales. Using electronic relaxation measurements combined with reaction-driven coherence signals, we determine that, after the photoexcitation of myoglobin (Mb) NO, the bond-br

β¦ Synopsis
The method femtosecond photoassociation spectroscopy (FPAS) is introduced and we report on its application to the study of the reaction Hg + Hg + hv ~ Hg 2. Our results demonstrate coherent bond formation obtained in the femtosecond time scale from free unbound reactants. The product Hg 2 is formed in the D1 u state and shows a high degree of rotational anisotropy induced by the polarization of the binding femtosecond pulse.

The appearance of coherent artifact signals in transient absorption spectroscopy employing a spectrally integrated detection system is studied. The influence of the detection design on the shape of the observed signal is detailed and the experimentally very important case, in which the shape of the
One of the degrees of freedom available to femtosecond time-resolved four-wave mixing spectroscopy is the geometry with which the polarization of the three independent lasers employed in this technique are oriented relative to one another. In the work presented here, different polarization geometrie
