Over the past few years a wealth of new information on the properties of temporary negative ions has become available through various electron scattering techniques. The present paper focuses on recent work involving electron transmission spectroscopy to probe low‐lying shape resonances in polyatomic systems. Emphasis is placed on new findings concerning the relative positions of π* and σ* resonances and dissociative attachment ( e − + AB → AB − → A + B − ) channels in unsaturated compounds. The theoretical questions raised by the experimental results are discussed.
