“…At very high energies, such as those investigated by Balashova et al [100] (30 keV N 2+ on Cu at 3-10 • to the (100) surface plane), the atoms of the molecule and those of the surface appear as point-like particles and the intramolecular interactions are of reduced significance. Molecular-axis orientation effects appear here as well [101,102], but their origin is trivial.…”

The role of the orientation of a molecule in its interaction with a surface is examined for a number of cases. At first the determination of the static orientation of a molecule at the surface is discussed. A dependence of the orientation on state and coverage is found for O 2 molecules adsorbed on Ag(110). The orientation dependence of NO in chemisorption, displacement reactions, and chemical reactions is discussed. Rotational excitation of NO in collisions with surfaces is shown to exhibit a strong orientation dependence. Dissociative chemisorption of hydrogen molecules is found to depend on the initial orientation of the molecule. Finally, in dissociative collisions of fast molecules with surfaces the role of the initial orientation is examined and the final orientation of the molecular axis is determined. Several mechanisms for molecular dissociation are discussed.

“…Since the direction of the molecule's axis can coincide with or be opposite to its direction of motion, the solid angle equals AS Q = 2 z , Assuming that all orientations of the incident molecule are equally probable, from (10) one gets the following formula for the probability of the molecule being scattered by a single atom without dissociation?…”

Collision of water molecule ions with solid surfaces can result in neutralization and fragmentation of the molecule. The energy distribution of total scattered yield was measured with a time-of-tlight mass spectrometer. The major spectral peak energy is close to the value expected for a binary collision of OH with a copper atom, and the energy distribution can be accounted for by the existing dissociation models. Comparisons are made between the scattering of water molecule ions and that of He' and Ne' ions in terms of the spectral full width at half-maximum, shape and the scattered yield It is found that significant water vapour neutral peaks appear in the spectra of scattered Ne. This implies that strong non-resonance charge exchange mechanisms occur in the projectile beams. The spectral peak heights of the water ion and neutral scattered at different incident angles are compared to those of Ne.
