Abstract
The quantum dynamics of free electrons interacting with diacetylene molecules (HCCCCH) under the conditions observed in planetary atmospheres (like those of Titan and Uranus) is analyzed using two different ab initio interaction and multichannel scattering methods as described in the main text. The locations of π ∗ and σ ∗ resonances, and their spatial features, are obtained with the clear presence of a low-energy (~2 eV) resonant state of π* u symmetry being established with both computational methods. The consequences of such findings with respect to the interstellar medium (ISM) observations are discussed and further model studies for dissociative anionic stabilization paths are suggested.
