Abstract
New time and energy resolved spectra of the L' 2Φ-X2π (0,v') bands of NO in Ar and Kr matrices are reported. The L'(0,v') bands are excited exclusively via the B'2Δ valence state and their lifetime is 3000±500 ns in both matrices. The quantum efficiency for L'(v=0) emission is estimated to be ≤0.04. The 2Φ-2π transition is discussed in terms of a statically induced transition moment involving spin-orbit mixing with B'2Δ, but also in terms of nonadiabatic matrix elements due to the coupling to the lattice. Relaxation down to L'(v=0) is discussed in terms of matrix-induced interstate cascading with the b4ΔΣ- state.
