The behavior of the secondary electron emission (SEE) from organic solids has been considered. It has been shown that the maximum SEE yields of many hydrocarbon compounds exponentially depend on the extinction coefficient of secondary electron defined by the π‐electron fraction in molecule, which is correlated to Dionne's theoretical equation. The concept that the extinction coefficient of secondary electron is represented in terms of the fraction of the delocalized and low energy‐gap electron‐like π‐electron will be convenient for a rough estimation of the SEE yield of other various materials. On the other hand, a novel universal equation representing the normalized SEE yield curve has also been proposed in this paper, by which an analysis of the normalized SEE yield curves of many organic solids have been tried.
