Temperature dependence of fine-structure resolved de-excitation rate coefficients for NH in collision with para-H2 (solid) and ortho-H2 (dashed). The fine-structure conserving transitions (∆n1 = ∆j1) are presented in the top panel; the fine-structure changing transitions (∆n1 ≠ ∆j1) are shown in the bottom panel.
