Orientation in molecule - surface interactions

Abstract

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.

Energy transfer and chemical dynamics at solid surfaces: The special role of charge transfer

“…The reader might be understandably dissatisfied with our limited efforts to provide an overview and a context for this vast field. Fortunately, others have provided similar contributions to this one and the reader is referred to that additional review literature not otherwise cited below [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27].…”

Orienting polar molecules without hexapoles: Optical state selection with adiabatic orientation

“…Nowhere has the desire to understand orientational impacts on function driven scientific investigation more than in the field of surface chemical dynamics [1][2][3][4][5][6]. In addition to the following reviews, to which the reader is directed [7,8], specific examples of studies include orientational influences on rotational inelastic energy transfer in molecule-surface collisions [1,2]. In addition, orientation influences sticking at surfaces.…”

Steric Effects in the Scattering of Oriented CH3Cl Molecular Beam from a Graphite Surface: Weak Interaction of Physisorption

“…In particular, the steric effect on the interaction of polyatomic molecules from surfaces is one of the central topics in the fields of organic chemistry, catalytic chemistry, biochemistry, and so on. Although there are a lot of studies on the steric effects of diatomic molecules on surfaces, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][26][27][28][29][30][31][35][36][37]41 the works on polyatomic molecules are rare. 1,[17][18][19][20][21][22][23][24][25][31][32][33][38][39][40] The steric effects of a polyatomic system was first reported by Novakoshi and McClelland in the CF 3 H scattering from Ag(111) surface.…”
