785GHz. *Lower panel:* $J = \tfrac{3}{2} - \tfrac{1}{2}$ component at ca. 787GHz. The filled grey histograms show the observed spectra, while the blue trace is our HFS fit. The red sticks represent the position of the HFS components assuming LTE intensities.[]{data-label="fig:nd2_21"}](nd2_2-1_15-05.pdf "fig:"){width="\hsize"}
