Abstract

Collision reactions between the cyano radical (CN) and unsaturated hydrocarbons (C₂H₂), which occur in the atmosphere of Saturn's moon Titan, were investigated using ab initio molecular dynamics (AIMD) simulations. The simulation results were categorized into three kinds: nonreactive collision, incorporation, and substitution. Short-time Fourier transform analysis of velocity auto-correlation functions obtained by the AIMD simulations was performed to examine the non-equilibrium condition of the vibrational states. Spectrograms, which correspond to the time evolution of power spectra, clarify the relationship between the three reaction channels and the dynamical changes of the vibrational states.
