Fig. 1

Selection of the spectra observed towards the pre-stellar core L1544 (black) and the protostellar core HH211 (red). The dotted vertical lines indicate the respective rest velocities of the cores. For HCN, the F = 2–1 transition is shown. For CCH, C¹³CH CCD H¹³CN and DCN, the transitions listed in Table 1 are shown.
