Electron-impact vi->vf vibrational excitations cross sections, involvingrovibrationally excited N_{2}(v_{i}, J) and NO(v_{i}, J) molecules (fixed J),are calculated for collisions occurring through the nitrogen resonantelectronic state N_{2}^{-} (X ^{2}\Pi_{g}), and the three resonant states ofnitric oxide NO^{-}(^{3}\Sigma^{-},^{1} \Delta,^{1} \Sigma^{+}). Complete setsof cross sections have been obtained for all possible transitions involving 68vibrational levels of N2(X ^{1}\Sigma^{+}_{g}) and 55 levels of NO(X ^{2}\Pi),for the incident electron energy between 0.1 and 10 eV. In order to study therotational motion in the resonant processes, cross sections have been alsocomputed for rotationally elastic transitions characterized by the rotationalquantum number J running from 0 through 150. The calculations are performedwithin the framework of the local complex potential model, by using potentialsenergies and widths optimized in order to reproduce the experimental crosssections available in literature. Rate coefficients are calculated for all the(v_{i}, J) \rightarrow (v_{f}, J) transitions by assuming a Maxwellian electronenergy distribution function in the temperature range from 0.1 eV to 100 eV.All the produced numerical data can be accessed athttp://users.ba.cnr.it/imip/cscpal38/phys4entry/database.html.
