Negative ion formation through electron transfer in collisions between K(nd) Rydberg atoms (10 $\leq$ n $\leq$ 110) and C$\sb7$F$\sb{14}$ and 1,1,1-C$\sb2$Cl$\sb3$F$\sb3$ is studied and provides a novel means to explore electron capture by these molecules at sub-thermal energies. The data suggest electron attachment to C$\sb7$F$\sb{14}$ occurs through two channels, one leading to the formation of long-lived C$\sb7$F$\sb{14}\sp-$ ions and the other to C$\sb7$F$\sb{14}\sp-$ ions that experience rapid autodetachment. On the other hand, electron attachment to 1,1,1-C$\sb2$Cl$\sb3$F$\sb3$ results directly in dissociation and the formation of Cl$\sp-$ ions. The present data are discussed in light of earlier results obtained with swarm and threshold photoelectron spectroscopy techniques.
