Photoionization-efficiency studies of some simple inorganic molecules
Abstract
The supersonic molecular beam method yielded more precise values of the ionization energies (IEs) of HgX2(+) (X = Cl, Br, and I) to within + or - 3 MeV. Lower resolution studies of the HgX2 fragment ions were undertaken and values of the binding energies of HgX(+) and HgX were calculated from the measured appearance energies (AEs) of HgX and X(+). In addition, photoionization, studies of the CO2, N2O, CO, N2, NO, and O2 dimers and clusters yielded the IEs of (CO2)/sub n = 2-4/, (N2O)2, (CO)/sub n = 2,3/, (N2)/sub n = 2,3/, and (NO)/sub n = 2-6/, and the AEs of N2O3(+) from (N2O)2, O3(+) from (O2)2, O5(+) from (O2)3, and O7(+) from (O2)4. Analysis of the PIE curves of (CO2)2(+) and (N2O)2 indicates that electronic predissociation may be an important dissociation mechanism for some Rydberg dimers. Solvation energies of NO(+) by one to five NO molecules were determined. Analysis of the PIE spectra for O3(+), O5(+) and O7(+), provided insights concerning the internal energy effects on ion-molecular half reactions.
