The nuclear hyperfine structure constants and the electric dipole moment of hydrogen fluoride, H/sup 1/F/sup 19/, in the ground-vibration and first excited rotation state were measured in a molecular beam electric resonance experiment. The hfs constants are: c/sub F/ = 307.6 plus or minus 1.5 kc, c/ sub p/ = --70.6 plus or minus 1.3 kc, /sup 2//5g/sub p/gF mu /sub nm//sup 2//h (r/sup 3/) = 57.6 plus or minus 0.44 kc. The apparatus was calibrated by observing Stark transitions in the ground-vibration and first excited rotation state of carbonyl sulfide. O/sup 16/C/sup 12/S/sup 32/, that gave mu /sub HF// mu /sub OCS 0,0037, or mu /sub HF/ = 1.8195 plus or minus 0.0026 D, by using mu /sub OCS/ = 0.7124 plus or minus 0.0002 D. An absolute measurement of the OCS electric dipole moment gave mu /sub OCS/ = 0.7120 plus or minus 0.003 D. A digitally computed solution of the Stark effect with magnetic hyperfine structure was necessary to interpret the data. The theory and experiment are in good agreement over the range of electric-field strengths used in the experiment. The hfs constants are in excellent agreement with the averaged absolute values of these constants as measured in a molecular beam magnetic resonance experiment. The agreement has significance because of discrepancies between the results from the two resonance methods, for some other molecules, in previous experiments. (auth)
