“…For example, the angular dependence of the initial trapping probability of Xe on Pt( 111) deviates from "normal energy" scaling3•4 and requires a more complex potential function for theoretical simulations. 3 Similar results have been obtained for argon trapping on a hydrogen (H) saturated W(100) surface.1 In addition, the initial trapping probability of Xe on Pt(111) at normal incidence decreases much more slowly with increasing incident translational energy than predicted by the one-dimensional theory based on the master equation. 6 In order to account for the incident angle and translational energy dependence of the initial trapping probability of Xe on Pt( 111), it was necessary to utilize threedimensional stochastic trajectory calculations employing a Morse potential.3…”

A pedagogic review of technology used to orient polar molecules is presented to place in context the report of a new approach to this problem. Laboratory frame orientation of polar molecules is achieved by state-specific optical pumping in a region free of electric fields followed by adiabatic transport into a static electric field. This approach overcomes some of the limitations of the more common hexapole focusing method. In particular the method is nearly insensitive to the kinetic energy of the sample. We demonstrate production of oriented samples of NO (l el = 0.15 D) with translational energies above 1 eV in both high-and low-field seeking states. The method can be extended to many other classes of molecules, including near symmetric tops and ions.

“…Quadrupole state selection and orientation is limited to a small number of diatomic molecules with very large dipole moments, and is discussed in detail by Toennies and coworkers. 21 Here we will focus on the hexapole state selector. This has been used to prepare spatially oriented samples of a wide range of molecules, including the methyl halides, NO, OH, and even, recently, the asymmetric top propylene oxide.…”

The gas phase is generally defined as a state of matter in which atoms or molecules are in constant, rapid, random Brownian motion. However, a range of techniques exist for preparing distributions of gas phase atoms and molecules whose motion is far from random, and whose orientation in space is well defined. In this Perspective, we will explore the nature of atomic and molecular alignment and orientation, the various techniques by which samples of spatially oriented species may be prepared and characterised, and some of the ways in which oriented molecules are being exploited to further our knowledge of molecular structure and dynamics.
