Molecular beam apparatus to study interactions of oriented NO and surfaces

A molecular beam apparatus to study molecule-surface dynamics is described. A pulsed molecular beam is first state-selected by electrostatic focusing and subsequently oriented with either the N-end or with the O-end towards the surface before it interacts with a Pt(111) or Ag(111) surface. The theor...

Description
Summary:A molecular beam apparatus to study molecule-surface dynamics is described. A pulsed molecular beam is first state-selected by electrostatic focusing and subsequently oriented with either the N-end or with the O-end towards the surface before it interacts with a Pt(111) or Ag(111) surface. The theoretical analysis is given predicts the degree of orientation. The analysis is verified by measuring the electric field dependence of the orientational effect upon the surface scattering process. Good agreement is obtained.
