摘要: We have measured relative excitation functions for the production of electronically excited fragments by electron impact dissociation methane, ethylene and methanol from 0 to 2000 eV. At low energies, 10–50 eV, appearance potentials are correlated specific limits and, when possible, states parent molecules. It is found that below ∼25 eV superexcited play dominant role in producing these fragments. Fano plots been constructed determine types molecular involved. In general, most produced through optically forbidden transitions.
