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 bF(25Mg) = -317.8 (4.9) MHz, indicating a large electron density at the magnesium nucleus.
