Photodissociation of Alkyl Iodides in Helium Nanodroplets I: Kinetic Energy Transfer

Marcel Drabbels, Andreas Braun

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 ...

Photodissociation of Alkyl Iodides in Helium Nanodroplets II: Solvation Dynamics

Marcel Drabbels, Andreas Braun

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 ...

A New Sensitive Detection Scheme for Helium Nanodroplet Isolation Spectroscopy: Application to Benzene

Marcel Drabbels, Evgeniy Loginov, Andreas Braun

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 ...

Photodissociation of Alkyl Iodides in Helium Nanodroplets III: Recombination

Marcel Drabbels, Andreas Braun

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 Simple Procedure to Extract Speed Distributions from Ion Images with a Large Background Contribution

Marcel Drabbels, Andreas Braun

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 ...
