The theoretical transition probabilities between the B 3Π g and the A 3Σ u+, W 3Δ u, B′ 3Σ u− states of N 2

Abstract

The electronic transition moment functions between the B 3Π g state and the A 3Σ u +, W 3Δ u, B′ 3Σ u − states of N 2 are studied using the internally contracted multireference configuration interaction method based upon complete active space SCF reference wavefunctions. The dependence of the moments on both the one and n-particle basis sets has been investigated in detail. The calculated radiative lifetimes for the vibrational levels of the B 3Π g state are in excellent agreement with the most recent data published for υ′ = 5 to 12, measured by laser induced fluorescence, and for υ′ = 0, measured by electron impact induced fluorescence.
