In this paper, we study single and double ionizations of N2O in a short elliptically polarized 800 nm laser pulse using the COLTRIMS technique. The molecular-frame photoelectron angular distribution and the ion sum-momentum distribution of single and double ionizations of N2O molecules are reported for the single ionization dissociative channel NO[Formula: see text] + N and the double ionization dissociative channel NO[Formula: see text] + N[Formula: see text]. The ionizations of multiple orbitals for the two studied dissociative channels were identified via studying the orientation dependent ionization rates for their KERs. The results show that the shape of the ionizing orbitals governs the single and double ionization processes of N2O.

Disulfide bonds (–S–S–) are severely damaged as a consequence of sulfur core–shell ionization processes, which is related to their low thermodynamic stability in multiply-charged systems.

Threshold Energies

The photoionization curves and the threshold energies for the molecules vinylchloride, vinylfluoride, 1,1-difluoroethylene and their abundant fragment ions have been measured with synchrotron radiation in the photon energy range from 10 - 23 eV. Appearance potentials were used to calculate heats of formation, bond energies and ionization potentials. The structure of ion efficiency curves is discussed in terms of different ionization processes.
