Angular distributions for the inelastic scattering of NO(X(2)Π) with O2(X(3)Σg(-))
The inelastic scattering of NO(X<sup>2</sup>Π) by O<sub>2</sub>(X<sup>3</sup>Σ<sub>g</sub><sup>-</sup>) was studied at a mean collision energy of 550 cm(-1) using velocity-map ion imaging. The initial quantum state of the NO(X<sup>2&...

| description | The inelastic scattering of NO(X<sup>2</sup>Π) by O<sub>2</sub>(X<sup>3</sup>Σ<sub>g</sub><sup>-</sup>) was studied at a mean collision energy of 550 cm(-1) using velocity-map ion imaging. The initial quantum state of the NO(X<sup>2</sup>Π, v = 0, j = 0.5, Ω=0.5, 𝜖 = -1, f) molecule was selected using a hexapole electric field, and specific Λ-doublet levels of scattered NO were probed using (1+1(&apos;)) resonantly enhanced multiphoton ionization. A modified "onion-peeling" algorithm was employed to extract angular scattering information from the series of "pancaked," nested Newton spheres arising as a consequence of the rotational excitation of the molecular oxygen collision partner. The extracted differential cross sections for NO(X) f→f and f→e Λ-doublet resolved, spin-orbit conserving transitions, partially resolved in the oxygen co-product rotational quantum state, are reported, along with O2 fragment pair-correlated rotational state population. The inelastic scattering of NO with O<sub>2</sub> is shown to share many similarities with the scattering of NO(X) with the rare gases. However, subtle differences in the angular distributions between the two collision partners are observed. |
