Resonantly enhanced multiphoton ionization of nitrogen a''1.SIGMA.g+ (v' = v'') .rarw. X1.SIGMA.g+ (v'' = 0, 1, 2). 2. Alignment and orientation measurements

Abstract

The N 2 a'' 1 Σ g + ←X 1 Σ g + (0,0) 2+1 resonance-enhanced multiphoton ionization (REMPI) transition has been used to measure angular momentum alignment and orientation of N 2 scattered from Ag(111). This two-photon Σ←Σ transition has been used for the first time to measure angular momentum alignment and orientation moments. Alignment of N 2 molecules has been measured using the O, Q, and S branches, and orientation has been measured using the O and S branches
