Abstract

Rotational spectra of the magnesium and chlorine isotopomers of MgCl (X ²ε{lunate}⁺) have been measured in the frequency range 260-380 GHz using direct absorption techniques. The species studied (²⁵Mg³⁵Ml, ²⁵Mg³⁷Cl, and ²⁶Mg³⁷Cl) were created in a dc glow discharge by the reaction of magnesium vapor with CCl₄. Several rotational transitions were recorded for each isotopomer, and fine structure, as well as hyperfine splittings due to the ²⁵Mg nucleus, were observed. Rotational, spin-rotation and hyperfine constants were determined for these radicals. The average value of the Fermi contact terms was b_F(²⁵Mg) = -317.8 (4.9) MHz, indicating a large electron density at the magnesium nucleus.
