Abstract

A high resolution optical spectroscopic study of a molybdenum mononitride, MoN, supersonic molecular beam sample has been performed. The R_ee (0.5) branch feature of the (0,0) A ⁴Π_3/2-X ⁴Σ_1/2^- band system for ⁹⁸MoN was recorded as a function of static electric field strengths of up to 3.5 kV/cm. The splittings and shifts were analyzed to produce values of the permanent electric dipole moment of 4.56(9) and 3.38(7)D for the A ⁴Π_3/2 and X ⁴Σ_1/2 ^- states, respectively. The field free splittings for the ⁹⁵MoN and ⁹⁷MoN isotopic forms were interpreted as arising from X ⁴Σ_1/2^- magnetic hyperfine effects and the resulting spin density of 5.09(8) a.u.^-3 was determined. Comparisons with predictions from theoretical models are given.
