State-to-state differential cross sections for rotationally inelastic collisions of NO(2Π1/2,j⩽2.5) with CO(1Σ+) and O2(3Σg−) at a kinetic energy of 442 cm−1

Crossed molecular beam measurements of state-resolved differential cross sections for NO+O2 and NO+CO inelastic collisions at a relative kinetic energy of 442 cm−1 are reported. The initial states (NO 2Π1/2, ν=0, j⩽2.5, CO 1Σ+, ν=0, O2 3Σg−, ν=0) were prepared by pulsed supersonic expansions of pure NO, O2, and CO gas. Scattered NO products were detected by resonance enhanced two-photon ionization. Product distributions were measured in both center-of-mass scattering angle and final rotational state (j′). Intensity maxima were found in both types of scans and comparable populations were found in both of the spin–orbit manifolds (2Π1/2 and 2Π3/2). The results are compared to previous inelastic scattering experiments of NO collisions with NO, Ar, CO, and O2.
