Investigation of steric effects in inelastic collisions of NO„X 2P... with Ar
Cross sections were determined for collisions of Ar with oriented NO(X P), based on full close-coupled calculations and new ab initio potential energy surfaces ~PESs!. Collisions in which the NO molecules are initially oriented so that the O end preferentially points toward the Ar atom are more effective in promoting spin–orbit changing transitions. The magnitude of the steric asymmetry is cons...
متن کاملState-resolved diffraction oscillations imaged for inelastic collisions of NO radicals with He, Ne and Ar.
Just as light scattering from an object results in diffraction patterns, the quantum mechanical nature of molecules can lead to the diffraction of matter waves during molecular collisions. This behaviour manifests itself as rapid oscillatory structures in measured differential cross-sections, and such observable features are sensitive probes of molecular interaction potentials. However, these s...
متن کاملRotationally elastic and inelastic dynamics of NO(X2Π, v = 0) in collisions with Ar.
A combined theoretical and experimental study of the depolarization of selected NO(X(2)Π, v = 0, j, F, ɛ) levels in collisions with a thermal bath of Ar has been carried out. Rate constants for elastic depolarization of rank K = 1 (orientation) and K = 2 (alignment) were extracted from collision-energy-dependent quantum scattering calculations, along with those for inelastic population transfer...
متن کاملElastic e-NO collisions.
In this paper we use the Schwinger multichannel method ~SMC! to calculate several types of cross sections related to the elastic electron scattering by NO. We show through the NO system that the elastic scattering of an electron by an open shell molecule is a much richer process than the corresponding scattering by closed shell targets. We present cross sections for unpolarized electron scatter...
متن کاملMolecular reorientation in collisions of OH + Ar.
Orientational effects in rotationally elastic collisions of OH with Ar were studied in a crossed molecular beam setup. A static electric field was applied to orient the molecules before the collision. After the collision the orientation was measured by using a narrow-band laser system to probe the Stark-split states corresponding to different orientations. Differential and integral cross sectio...
