| | Ten //a//-type lines with 1 ≤ //J// ≤ 7 and //K<sub>a</sub>// ≤ 4 between 41 and 150 GHz were identified for the main <sup>24</sup>Mg isotopolog employing the Yebes 40 m and IRAM 30 m dishes in the couses of molecular line surveys of CW Leonis. These lines have good to reasonable signal-to-noise ratios, and several lines are unblended. One and three lines were identified for the <sup>25</sup>Mg and <sup>26</sup>Mg minor isotopologs, respectively. The isotopic ratios are compatible with solar values within uncertainties. The derived MgC<sub>2</sub> : MgC<sub>2</sub>H : MgC<sub>4</sub>H : MgC<sub>6</sub>H abundance raios are about 1 : 2 : 22 : 20.\\ |
