Abstract
The energy values of some doubly ionized states of CH4, N2O, C2N2, C2H2, C2H4, C2H6, C3H8, C6H6, CH3OH are determined by measuring the translational energy spectra of H- ions arising from single collision double charge transfer of 4 keV protons on these molecules. Assignments of the measured values to given states of the doubly ionized molecules are discussed. A comparison of the ionization potentials of the neutral and singly ionized molecule is made for some of the molecules.Keywords
