Abstract
State-selected molecular beams of ND3 in antisymmetric inversion states (formula available in paper) are scattered on a graphite (0001) surface at T8 = 130K. A preponderance of symmetric inversion states, (formula available in paper), is observed in the directly scattered molecules. The observed effect is an interference on a surface potential between the left and right inversion configurations of a single molecule which are oppositely oriented with respect to the surface. A procedure leading from the experimental data on this molecular self-diffraction to an approximate analytical molecule-surface potential is suggested. This procedure, which is based on the infinite order sudden approximation (Gerber et. al., J. Chem. Phys. 73, 4397 (1980)), requires experimental study of the inversion symmetry change for several initial rotational states as a function of translational energy.
