Notes. The spectroscopic information of both SO2 and 34SO2 are taken from CDMS (Müller et al. 2001, 2005; Endres et al. 2016). The entry of SO2 was mostly based on the work of Müller et al. (2005) and the entry of 34SO2 is based of several spectroscopic works (e.g., Lovas 1985; Belov et al. 1998, for transitions at ALMA Band 7 frequencies). The last column indicates whether the specific transition was detected (Y), blended (B), or not detected (N).
