We present results of effective range theory calculations of nondissociative electron attachment to SF6 molecules and CO2 clusters. The first process is strongly influenced by the SF virtual state, and the second by vibrational Feshbach resonances associated with electron capture by the long-range polarization field of the cluster with simultaneous vibrational excitation of one molecular unit. We also study how both processes depend on the initial vibrational excitation of the target. We obtain a noticeable dependence of the attachment cross-section on the symmetric stretch vibration of SF6, although it does not lead to a significant temperature dependence at low electron energies.
