Chromium mononitride molecules have been produced in a laser vaporization molecular beam source using Cr metal and ammonia. The complex CrN LIF spectra between 430 and 490 nm have been examined in detail and representative bands in three new electronic subsystems, labeled B 4Σ- ← X 4Σ-, d 2Π3/2←X 4Σ-, and d 2Π1/2←X 4Σ-, have been rotationally analyzed. Perturbations between the B 4Σ- and d 2Π states and their dependence on vibrational quantum numbers have been examined. Dispersed fluorescence (DF) spectra have been recorded which provided a measure of the state mixing. The DF spectra also reveal the presence of an electronic state of CrN with T～6000 cm-1, identified as the a 2Σ- state. Molecular parameters in the B 4Σ-, d 2Π, and a 2Σ- states have been established.

The Pe(1), F = 2.5 branch feature of the (0,0) D 3Π0e - X 3Δ1 band system of 51 VN was recorded as a function of an applied static electric field. The resultant Stark splitting and shifts were analyzed giving values of 3.07(7) D and 6.1(4) D for the X 3Δ1 and D 3Π0e states, respectively, for the magnitude of the permanent electric dipole moment, μ. Similarly, the Ree(0.5) branch feature of the (0,0) A 4Π3/2 - X 4Σ- band system of 52 CrN was recorded as a function of an applied static electric field and analyzed to produce μ values of 2.31(4) D and 5.42(2) D for the X 4Σ- and A 4Π3/2 states, respectively. In order to facilitate the dipole moment determinations for 52CrN it was necessary to record and analyze the field free spectrum of the (0,0) A 4Π3/2 - X 4Σ- subband system. A comparison of the dipole moments for the first row monoxides and mononitrides is made and trends are discussed with reference to a molecular orbital correlation scheme.
