Abstract

This article focuses on the charge transfer (CT) dynamics in low-energy collisions between nitrogen ions (N₂⁺/N⁺) and water molecules (H₂O) within a collision energy range of 0.42–2.09 eV, investigated using three-dimensional ion velocity map imaging (3D-VMI). The study identifies two distinct CT mechanisms: resonant CT dominating at higher collision energies through large-impact-parameter collisions, and intimate, small-impact-parameter collisions at lower energies involving transient intermediate complexes (N₂⋯H₂O)⁺ or (N⋯H₂O)⁺ that facilitate energy redistribution. Absolute cross sections for the N₂⁺ + H₂O → N₂ + H₂O⁺ reaction are provided, with implications for modeling ion–molecule interactions relevant to planetary atmospheres and astrochemical environments.
