Notes. The molecular data are taken from the Cologne Database for Molecular Spectroscopy (CDMS; Müller et al. 2001; Endres et al. 2016). Column 1 reports the rest frequency of the transition; column 2 the molecular species; column 3 the quantum numbers; column 4 the upper state energy. The quantum numbers are given depending on the symmetry of the molecule: J^upper − J^lower for linear, $J_{K}^{upper} - J_{K}^{lower}$ $Mathematical equation: $\[J_{K}^{\text {upper}}-J_{K}^{\text {lower}}\]$$ for symmetric top, and $J_{K_{a}, K_{c}}^{upper} - J_{K_{a}, K_{c}}^{lower}$ $Mathematical equation: $\[J_{K_{a}, K_{c}}^{\text {upper}}-J_{K_{a}, K_{c}}^{\text {lower}}\]$$ for asymmetric top molecules.
