Forming (NCCN)− by quantum scattering: A modeling for Titan's atmosphere

► Quantum description of the electron attachment to NCCN. ► Stabilization paths for the (NCCN)− after the attachment of environment electrons. ► Electrons in the energy range of observed distributions in the Titan's atmosphere. ► One resonance found at very low energy and with a very large lifetime. ► Effects of the stretching and bending deformations of the NCCN molecule.
