CH₂NH, NH₂CHO and NHCHO transitions detected towards NGC 6334I. Orange, magenta, red and green lines represent the synthetic spectrum of CH₂NH, NH₂CHO and NHCHO and the sum of spectra of other contributing species respectively. The abscissa is the rest frequency with respect to the radial velocity towards each of the hot cores (listed in Table 2). The data are shown in black. Top panels: MM1 II. Middle panels: MM2 I. Bottom panels: MM3 I.
