✦ Synopsis

The v3 fundamental band of SHf has been observed in absorption in a hollow cathode discharge with a difference frequency laser system. The molecular constants of the ground state have been determined through a fit of the ground-state combination differences (from the observed transition frequencies). The band is perturbed and a preliminary analysis is made to obtain the molecular constants for the excited state. The lowest rotational transition frequency useful for astrophysical searches is predicted to be 293464( 3) MHz.
