Article Description

The magnetic properties of the B spin component of the A state in the molecule CS have been investigated with a resolution of ∼ 100 kHz by quantum beat spectroscopy in a supersonic jet. Zeeman-level tuning in CS and CS, providing Landé g factors, and measurements of the CS nuclear hyperfine structure were carried out, particularly to investigate their J dependence. Based on these results, it is proposed that both the magnetic moment and the hyperfine splitting are dominated by spin-uncoupling interactions, described in the rotational Hamiltonian by B( J - S). In addition, the g factors and rotational state lifetimes were used to provide spectroscopic assignments and to elucidate details of the state mixing. © 1992 American Institute of Physics.
