 Title: HYPERFINE STRUCTURE OF THIOFORMALDEHYDE Creators: Fabricant, Barbara; Muenter, J. S. Issue Date: 1976 Publisher: Ohio State University Abstract: Molecular beams of thioformaldehyde, $H_{2}CS$, have been generated by pyrolysis of dimethyl disulfide in a quartz beam source. A large number of transitions in both ortho and para states have been observed, Hyperfine structure has been resolved for the $M = \pm 1$ to $M = 0$ transition for the $1_{1}0, 2_{1}1$, and $3_{12}$ rotational levels. These data yield the dipole moment, spin-spin interaction and spin-rotation interactions. In principle, these three transitions allow the determination of the three spin-rotation tensor elements. However, the very near symmetric top nature of thioformaldehyde makes this information very strongly correlated. This problem will be discussed for electric resonance measurements for other $C_{2V}$ molecules such as ketene.
