The pure rotational spectrum of MnF has been measured in its X 7Σ+ ground state using millimeter/sub-millimeter direct absorption methods. Five and six rotational transitions, respectively, were recorded for this radical in its v=0 and v=1 states in the range 338-630 GHz. MnF was created from SF6 and manganese vapor, produced in a Broida-type oven. The species exhibited a complex pattern where the fine and 55Mn and 19F hyperfine structures are intermixed. Rotational, spin-rotation, spin-spin and hyperfine parameters have been determined for MnF. These constants have been interpreted in terms of bonding and electronic structure in metal fluorides.
