Spectra of the ortho-NH₂D (1_1, 0–0_0, 0) and para-NH₂ (1_1, 0–1_0, 1J = 1/2–1/2, F = 3/2–3/2) (a) and HDO (1_0, 1–0_0, 0) and (1_1, 0–1_0, 1) (b) lines observed with ALMA toward the SW image of PKS 1830−211. The labels in parenthesis (14), (19A), and (19J) stand for observations done in 2014, 2019 April, and 2019 July, respectively. The spectra of p-NH₂, (19J), and (14) were scaled down in opacity by factors 5, 50, and 75, respectively. The hyperfine structure of the ortho-NH₂D line (see Table A.4) is indicated, with the strongest hfs component centered at a velocity of −4 km s⁻¹.
