Fig. 2From: Analysis of velocity-mapped ion images from high-resolution crossed-beam scattering experiments: a tutorial reviewRotational energy level diagram of NO (X 2 ΠΩ ,v=0) radicals. Two spin-orbit manifolds exist with Ω=1/2 and Ω=3/2. Each rotational level is labeled by the rotational quantum number j, and is split into two Λ-doublet components with e and f parity. The energy splitting between the Λ-doublet components of each rotational level is greatly exaggerated for clarity. The NO radicals that exit the Stark decelerator almost exclusively reside in the j=1/2f stateBack to article page
