The formation of anionic species in the interstellar medium from interactionof linear molecules containing carbon, nitrogen and hydrogen as atomiccomponents (polyynes) with free electrons in the environment is modelled via aquantum treatment of the collision dynamics. The ensuing integral crosssections are employed to obtain the corresponding attachment rates over a broadrange of temperatures for the electrons. The calculations unequivocally showthat a parametrization form often employed for such rates yields a broad rangeof values that turn out to be specific for each molecular species considered,thus excluding using a unique set for the whole class of polyynes.

Electron-attachment rates for carbon-rich molecules in protoplanetary atmospheres: the role of chemical differences
