Vertical Ionization Potentials

The photoelectron spectra of diborane, hexadeuterodiborane, borazine and B -trifluoroborazine are presented, and adiabatic and vertical ionization potentials have been measured. The vibrational fine structure observed on some of the diborane bands is shown to be consistent with the forms of the molecular orbitals calculated by rigorous s.c.f. methods. The vertical i.p. of diborane are in better accord with a calculation which predicts a boron-boron bond in addition to the hydrogen bridge than with the calculations which indicate no direct boron-boron interaction. In borazine it is shown that the uppermost orbital is of π type rather than the σ type predicted by calculations, and that the extent of the π bonding, as measured by the energy separation of the π-type orbitals, is about 85 % of that in benzene. The effect of fluorination of borazine, as in benzene, is to stabilize the σ orbitals more than the π orbitals.

Bonding Characteristics

Helium 584 Å radiation produces photoeleetron spectra from water and deuterium oxide, which show extensive vibrational fine structure. The results are discussed in terms of the electronic structure of the molecule, and the bonding characteristics of the various molecular orbitals. Water is inferred to have only three configurationally distinct ionization potentials smaller than 21.22 eV.

Photoelectron Spectra

The 584 Å (21·22 eV) photoelectron, spectra of the following linear unsaturated molecules are reported: acetylene, dideutero-acetylene, hydrogen cyanide, deuterium cyanide, diacetylene, dideutero-diacetylene, cyanoacetylene, cyanogen, dicyanoacetylene, methylacetylene and dimethyltriacetylene. The ionization potentials of the molecules, and the vibrational fine structure observed in many of the bands, are discussed.
