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

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