Updated Zeeman effect splitting coefficients for molecular oxygen in planetary applications

摘要: Abstract We comment on a common practice to use pure Hund case (b) Zeeman parameters in planetary atmospheric radiative transfer applications involving molecular oxygen. A detailed theoretical formulation is presented for the splitting coefficients of oxygen its ground vibronic state, taking also relevant fine-structure interactions into account. The updated are compared simplified approach used earlier works. biggest differences between output these formulations occur states with low rotational energy, and greater 16O18O than 16O2. To get order magnitude error introduced by simplification coefficient computations, we perform limited study forward simulations few space-borne ground-based instruments. Our analysis shows that using introduces errors modelled radiation varying from insignificant up 10 K.
