Electrons of variable energy are attached to preformed clusters of CO2, N2O, H2O and SF6 in a molecular beam. The shape resonances of CO2 and N2O are found to be increasingly redshifted with increasing cluster size. Clusters of CO2, SF6 and H2O feature a resonance for near-thermal electrons; attachment at these energies does not cause intramolecular fragmentation. An additional resonance in the (N2O)- n yield is found at about 0.5 eV electron energy. Delayed autodetachment is suppressed in case of small CO2 and SF6 cluster anions, but not for the smallest observable H2O cluster anions (size n ≥ 12).
