Abstract

The low-rotational lines of the A Π2 -X Σ2 + (0,0) band system of the odd isotopologue of strontium monofluoride, S 87 rF, were recorded and analyzed. The S 87 r (I=9/2) magnetic hyperfine interaction is significant only in the |Ω| =1/2 spin-orbit component of the A Π2 state. Optical transitions appropriate for monitoring ultracold samples of S 87 rF are identified. The determined fine-structure parameters were used to predict the anisotropic magnetic g factor, gl, for the X Σ2 + (v=0) state. The g factors were used to predict the magnetic tuning of the N=0 (+parity) and N=1 (-parity) levels of the X Σ2 + (v=0) state. A comparison to spectroscopic parameters for the S 88 rF isotopologue is given.
