Spin-state abundance ratios of ammonia (left column), (middle column), and water (right column), including their respective deuterated forms, at a medium density of n(H2) = 104 cm−3 (top row), n(H2) = 105 cm−3 (middle row), and n(H2) = 106 cm−3 (bottom row). Solid lines represent the FS model, while dashed lines represent the PH model. The statistical ammonia spin-state abundance ratios are indicated with colored arrows.
