Electronic spectra of mono‐ and di‐negative aromatic ions

Abstract
The electronic spectra in the 32‐4 kK region of the mononegative ions of naphthalene, anthracene, tetracene, phenanthrene, diphenyl, terphenyl, quaterphenyl, pyrene, perylene, triphenylene and coronene are given. The spectra of the dinegative ions of anthracene, tetracene, terphenyl, quaterphenyl and perylene have also been investigated.
