CH₃NH₂ transitions detected towards NGC 6334I in the range 890.2 to 891.7 GHz (ALMA Band 10). The red line represents the synthetic spectrum of CH₃NH₂ assuming a column density of 2 × 10¹⁷ cm⁻², an excitation temperature of 100 K and a FWHM line width of 3.2 km s⁻¹, in a 00.′′26 × 0.′′26 beam (equivalent to the angular resolution of the data). The abscissa is the rest frequency with respect to the radial velocity towards the region (−7 km s⁻¹). The data are shown in black.
