    Notes:
    The adiabatic ionization potential of GeH+4 (GeH4) is measured by photoionization mass spectrometry to be ≤10.53 eV and perhaps as low as 10.44 eV. This is about 0.8 eV (∼9 vibrational quanta) lower than the value reported by photoelectron spectroscopy. This result, analogous to that found for SiH+4 (SiH4), implies a marked Jahn–Teller distortion of GeH+4. The appearance potentials of GeH+2 and GeH+3 from GeH4 are ≤10.772±0.009 eV and 〈11.657±0.01 eV, respectively. The reaction of F atoms with GeH4 generates GeH3, GeH2 (weakly), and some atomic germanium. The adiabatic ionization potential of GeH3 is ≤7.948±0.005 eV; that of GeH2 is ≤9.25 eV. Together with auxiliary information, limits (more probable values) of the incremental bond energies, in kcal/mol, are found to be D0 (H3Ge–H) 〈85.5 (82±2); D0 (H2Ge–H) 〉56.4 (59); D0 (HGe–H) 〈68.9 (66); and D0 (Ge–H) 〉53.7 (63). These specific bond energies, when appropriately normalized, display the same pattern as the SiHn (but not the CHn) bond energies and provide a basis for estimating the corresponding SnHn bond energies.

    Notes:
    The B2 H5 radical has been generated by the F+B2 H6 reaction, and studied by photoionization mass spectrometry. The photoion yield curve for B2H+5 (B2 H5 ) is extremely weak at the adiabatic threshold (∼6.945 eV), at least three orders of magnitude weaker than at its maximum (∼9.67 eV). This observation provides support for recent ab initio calculations, which predict a singly bridged B2 H5 and a triply bridged B2H+5 as ground states. Evidence is presented for the coexistence of a doubly bridged B2 H5 isomer, ∼3 kcal/mol higher in energy. From the appearance potential of B2H+3 (B2 H5 ), a B2 H5 –H bond energy of (approximately-less-than)102.7 kcal/mol is obtained. From the photoion yield curve of B2H+3 (B2 H5 ), at least one, and perhaps two, excited states of B2H+5 can be inferred. The lower one also branches into parent B2 H5, an apparent violation of QET.

    Notes:
    The dissociative ionization of HCOOH to form COOH+ +H+e has been reinvestigated. Experiments with DCOOH and HCOOD demonstrate that rearrangement competes with direct bond cleavage in this dissociation, even near threshold. Extrapolation of the photoion yield curve of COOH+ to the background level is ambiguous. A photoelectron–photoion coincidence experiment was thereupon performed, to obtain a breakdown diagram. From the 0 K cross over energy of 12.30±0.02 eV, we infer ΔHf00 (COOH+)=143.2±0.5 kcal/mol, and proton affinity (PA) (CO2)=129.2±0.5 kcal/mol. Some possible mechanisms for the rearrangement process are explored, but the calculated barriers are too high to explain the observation.

    Notes:
    B2H4 has been produced by the reaction of F atoms with B2H6, in successive abstraction reactions. The B2H4 species was detected and analyzed by photoionization mass spectrometry. The adiabatic ionization potential of this species (9.70±0.02 eV) and the vertical value (∼10.4 eV) are obtained from the photoion yield curve. These values, and the shape of this curve, are consistent with a doubly bridged, C2v structure for both the neutral and ionic species. The fragment ion B2H+2 is observed, with an appearance potential of 11.535±0.03 eV. This value, combined with previous results, yields D0(B2H4–H)≈40.1 kcal/mol, whereas D0(B2H5–H)(approximately-less-than)102.7 kcal/mol. The B2H+2 fragment may have as its neutral precursor an isomeric B2H4 (D2d), with approximately the same stability as the C2v species. An earlier value for the appearance potential of B2H+4 from B2H6 is shown to be too high, due to a very small formation probability at the thermochemical threshold.

    Notes:
    A photoionization mass spectrometric study has been performed on the products of the F+HCOOH, F+DCOOH, and F+HCOOD reactions. Hydrogen/deuterium abstraction on the carbon site yields the COOH/COOD radical which can be photoionized and detected. Abstraction on the oxygen site also occurs, but does not yield a detectable isomeric HCOO/DCOO product. Instead, CO2 is readily observed, implying that HCOO/DCOO is unstable to decomposition under the conditions of this experiment. The detection of COOH is believed to be the first experimental evidence for the stability of this species in the gas phase. An adiabatic ionization potential of 8.486±0.012 eV is obtained. Combined with the recently obtained ΔHf00 (COOH+)=143.2±0.5 kcal/mol, this ionization potential leads to ΔHf00 (COOH)=−52.5±0.6 kcal/mol. Hence, COOH is stable with respect to the lowest energy dissociation products (H+CO2) by 10.2±0.6 kcal/mol.
