Abstract The rotational spectrum of 24 Mg 35 Cl in its X 2 Σ+(ν= 0 and 1) state has been observed in the 14 GHz region by using a Fourier-transform microwave spectrometer combined with a laser-ablation source. The radical was produced by the reaction of atomic Mg vaporized by 532 nm laser light with Cl 2 diluted in Ar. The present observation of the lowest N transition by a high-resolving power instrument has provided accurate hyperfine ...
