Inelastic scattering of NO(AΣ) + CO: rotation-rotation pair-correlated differential cross sections.

A crossed beam velocity-map ion-imaging apparatus has been used to determine differential cross sections (DCSs) for the rotationally inelastic scattering of NO(AΣ, = 0, = 0.5) with CO, as a function of both NO(A, = 0, ') final state and the coincident final rotational energy of the CO.

Differential Cross Sections for Pair-Correlated Rotational Energy Transfer in NO(AΣ) + N, CO, and O: Signatures of Quenching Dynamics.

A crossed molecular beam, velocity-map ion-imaging apparatus has been used to determine differential cross sections (DCSs), as a function of collider final internal energy, for rotationally inelastic scattering of NO(AΣ, = 0, = 0.5) with N, CO, and O, at average collision energies close to 800 cm.

Non-intuitive rotational reorientation in collisions of NO(A Σ) with Ne from direct measurement of a four-vector correlation.

Stereodynamic descriptions of molecular collisions concern the angular correlations that exist between vector properties of the motion of the participating species, including their velocities and rotational angular momenta. Measurements of vector correlations provide a unique view of the forces acting during collisions, and are a stringent test of electronic-structure calculations of molecular interactions. Here, we present direct measurement of the four-vector correlation between initial and final relative velocities and rotational angular momenta in a molecular collision.
