Particle Beam Scattering From the Vacuum-Liquid Interface


Knowledge of the molecular-scale collision processes that determine chemical reaction dynamics at liquid surfaces is important for a complete understanding of a range of interfacial processes. The chapter details those research approaches that use directed beams of atoms and molecules to collide with liquid surfaces in vacuum. The chapter begins by discussing ways to satisfy the special requirements presented by conducting research with liquids in a vacuum environment. The contemporary experimental scattering approaches are surveyed, including methods based on time-of-flight mass spectrometry and laser spectroscopy. A discussion of the theoretical approaches to explain molecular scattering behavior ranges from simple kinematic models to fully atomistic direct dynamics simulations.
