Adsorption of chloromethane molecules on free argon clusters

Abstract

Binary chloromethane-argon clusters were investigated by means of synchrotron-radiation-based valence and core level photoelectron spectroscopies. The host argon clusters were produced by adiabatic expansion and exposed to chloromethane molecules using the pick-up technique. The study of the valence spectrum showed that heterogeneous clusters were formed. The spatial distribution of chloromethane in the clusters was determined through the analysis of core level photoelectron spectra recorded at the Ar 2p and Cl 2p thresholds and by comparisons with pure argon cluster and pure chloromethane cluster spectra. By analysing the peak positions, widths and integrated intensities of the cluster components we concluded that the chloromethane molecules are mainly located near surface sites.
