Detection of chloronium and measurement of the <sup>35</sup>Cl/<sup>37</sup>Cl isotopic ratio at //z// = 0.89 toward PKS 1830-211
Astron. Astrophys. 566, (2014) Art. No. L6.
The 111 –000 transitions of H235Cl+ and H237Cl+ were observed with ALMA redshifted from about 485 GHz to about 257 GHz. The 35Cl/37Cl isotopic ratio agrees within error bars with the terrestrial ratio.
