We present accurate <i>ab initio</i> calculations on several properties of a gas-phase system of interest in the interstellar medium (ISM), where the title molecular anion has been often surmised but not yet confirmed by observations. The CH<sup>-</sup><sup>3</sup>Σ<sup>+</sup> constitutes the smallest term in the series of longer anionic polyynes which have been observed in the ISM (e.g., C<sub>4</sub>H<sup>-</sup> and several others). Hence, its dynamical behavior in collision with He atoms, o ...[more]
