General concepts relating to, and recent advances in, the study of negative ions of polyatomic molecules are discussed with emphasis on halocarbons. The outline of the paper is as follows: basic electron attachment processes, modes of electron capture by molecules, short-lived transient negative ions, dissociative electron attachment to ground-state molecules, dissociative electron attachment to hot molecules (effects of temperature on electron attachment), parent negative ions, effect of density, nature and state of the medium on electron attachment, electron attachment to electronically-excited molecules, the binding of attached electrons to molecules (electron affinity), and the basic and the applied significance of negative-ion studies. 133 references.
