Potential energy, electric field gradient (EFG) at both nuclei, and electric dipole moment functions for the electronic ground states of NO+, NO and NO- were calculated at the internally contracted multireference configuration interaction (icMRCI) level using augmented correlation-consistent basis sets. The changes in the EFGŽs with internuclear separation R were used to interpret the character of bonding in the triad of NO species. The vibrational dependences of the electric properties were estimated and the EFGŽs were employed to determine the 14N nuclear quadrupole coupling constants. The effects of the choice of the basis set and reference configuration space were investigated. While the results obtained for NO+ and NO served primarily to assess the quality of calculations by comparison with available experimental and theoretical data, new information was obtained on NO-, including electric property functions and some notions about the existence of metastable states.
