The P_e(1), F" = 2.5 branch feature of the (0, 0) D ~3#PI#_(0e)-X ~3#DELTA#_1 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~3#DELTA#_1 and D~3#PI#_(0e) states, respectively, for the magnitude of the permanent electric dipole moment, |#mu#|. Similarly, the R_(ee)(0.5) branch feature of the (0, 0) A ~4#PI#_(3/2)-X~4#SIGMA#~- band system of ~(52)CrN was recorded as a function of an applied static electric field and analyzed to produce |#mu#| values of 2.31(4) D and 5.42(2) D for the X~4#SIGMA#~- and A ~4#PI#_(3/2) states, respectively. In order to facilitate the dipole moment determinations for ~(52)CrN it was necessary to record and analyze the field free spectrum of the (0, 0) A ~4#PI#_(3/2)-X~4#SIGMA#~- 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.
