We constructed semiempirical breakdown curves (BDC) for C$_2$N, C$_3$N, C$_2$N$^+$ and C$_3$N$^+$ molecules. These BDC, which are energy dependent dissociation branching ratios (BR) curves, were used to predict products branching ratios for various processes leading to the formation of C$_2$N$^{(+)}$ and C$_3$N$^{(+)}$ excited adducts. These processes, of astrochemical interest, are neutral-neutral and ion-molecule reactions, dissociative recombination and charge transfer reactions with He$^+$. Model predictions of BR are compared to the literature data and to reported values in the kinetic database for astrochemistry KIDA. With the new BR values, the C$_n$N abundances in cold cores were simulated.< Réduire
