M. Maierborst et al., ION MOBILITY MEASUREMENTS OF METAL HALIDE CLUSTERS, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 40(1-4), 1997, pp. 476-478
The failure of standard solid state methods to determine the structure
of very small clusters has been the starting point to adapt the ion c
hromatography technique to cluster experiments. A new approach combini
ng an ion drift cell and a time-of-flight mass spectrometer for cluste
r ion mobility measurements is described. In this publication we conce
ntrate on the experimental set-up and the data analysis starting with
the time-of-flight mass spectra. Furthermore, first results concerning
relative ion mobilities for cesium iodide and sodium iodide clusters
will be shown to demonstrate the feasibility of the new tandem instrum
ent.
