The photodissociation of (fluorinated) alkyl iodides in helium nanodroplets at a wavelength of 266 nm has been investigated by means of ion imaging techniques. It is found that a significant fraction of the created fragments escapes from the helium droplet ...
The recombination of fragments resulting from the photodissociation of (fluorinated) alkyl iodides in helium nanodroplets at a wavelength of 266 nm has been investigated by means of ion imaging techniques. It is found that in the case of CH3I an appreciabl ...
A new method is presented for recording excitation spectra of molecules embedded in helium nanodroplets. The method relies on the complete evaporation of the droplets following excitation of an dissolved molecule and the subsequent detection of the remaini ...
The solvation dynamics of non-thermal species in liquid helium has been investigated by photolyzing alkyl iodide molecules, CH3I, C2H5I and CF3I, embedded in helium nanodroplets. The iodine and CH3 fragments are found to leave the droplets solvated by a fi ...
We present a simple and robust procedure that allows extracting with high fidelity speed distributions from ion images that contain a large background contribution. The procedure requires no detailed knowledge about the background and is conveniently appli ...
A novel experimental apparatus to study the dynamics of photodissociation and photoionization processes in the interior or at the surface of helium droplets by means of imaging techniques has been designed, built and characterized. This molecular beam mach ...
The translational dynamics of CF3 in liquid helium have been investigated by photodissociating CF3I dissolved in helium droplets consisting of several thousands of atoms. The velocity distribution of CF3 fragments that have escaped from the droplets has be ...
