ELECTRON ATTACHMENT TO HETEROGENEOUS MOLECULAR CLUSTERS

Abstract

Heterogeneous clusters are unique model species enabling studies of bulk and surface processes by vacuum restricted methods. This is of particular importance for the reactions of low-energy electrons which have extremely short penetration depth in bulk environments. This contribution overviews our recent experiments with low-energy electrons and clusters prepared by different techniques. First, the deposition of molecules on argon nanoparticles enables the studies of electron induced chemistry of iron pentacarbonyl on the surface. These studies are relevant for the focused electron beam induced deposition - FEBID technique. Second, co-expansion of 2- nitrophenol with water was used to prepare multi-component systems of atmospheric relevance. Finally, using the gas humidification method, we have been able to prepare single micro-hydrated molecules of uracil and its analogues that mimic biological conditions. Specifics of the observed chemistry induced by low-energy electrons will be discussed.
