摘要: Abstract Molecular anions of variously substituted maleic and phthalic anhydrides (formed near 0 eV by secondary electron capture (electron beam > 15 eV)) react with the neutral anhydride to form 2M+ species. Certain also produce “excited” molecular in region between 1 5 eV. These ions do not INDO—MO calculations suggest that unreactive anion is one where extra occupies either ψ5 or ψ6 orbital.
