A high resolution optical spectroscopic study of a molybdenum mononitride, MoN, supersonic molecular beam sample has been performed. The [ital R][sub [ital ee]] (0.5) branch feature of the (0,0) [ital A] [sup 4][Pi][sub 3/2]--[ital X] [sup 4][Sigma][sub 1/2][sup [minus]] band system for [sup 98]MoN 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 [ital A] [sup 4][Pi][sub 3/2] and [ital X] [sup 4][Sigma][sub 1/2][sup [minus]] states, respectively. The field free splittings for the [sup 95]MoN and [sup 97]MoN isotopic forms were interpreted as arising from [ital X] [sup 4][Sigma][sub 1/2][sup [minus]] magnetic hyperfine effects and the resulting spin density of 5.09(8) a.u.[sup [minus]3] was determined. Comparisons with predictions from theoretical models are given.
