    Electric-field-enhanced laser-induced plasma spectroscopy of jet-cooled metal-based ion–molecule complexes (1991)

    Notes: Electric-field-enhanced laser-induced plasma spectroscopy is a relatively simple and general approach to the mapping of electronic states and internal mode structure in small metal-based molecular complexes. In an exemplary study, weakly bound excited-state ion–molecule complexes of aluminum have been formed and monitored. Emission spectra associated with Al+CO(Al+OC) and Al+H2 complexation show clear vibrational structure tentatively associated with the Al+ -molecule stretch and/or triatomic bending mode. These features are correlated precisely with transitions among several excited states of the Al+ ion which extend throughout the visible and ultraviolet. Evidence is also obtained for Al+N2 complexation associated with select Al+ excited states. All complex emissions which can be readily ascribed involve singlet-(Al+) –singlet-(CO,H2,N2) interactions. Resulting singly charged electronically excited molecular-ion complexes are likely formed in orbiting collisions of the Al+ ion. Observed vibrational-level separations are consistent with quantum-chemical calculations on the ground electronic 1Σ states of Al+CO, Al+OC, Al+H2, and Al+N2. Broadening and vibrational structure associated with an Al++–N2 interaction are apparent, as excited-state complex formation in this system dominates that for the Al++–CO interaction. These results are considered in view of an anticipated Coulomb explosion in multiply charged ions. Extensions to the vacuum ultraviolet for the study of weakly bound ground-state Al+ complexes and extrapolations to other metal-based systems are suggested.

    Self-flushing optical window to prevent collection of condensates (1986)
    [S.l.] : American Institute of Physics (AIP)

    Notes: As an aid to the characterization of nominally condensible and/or high-temperature molecules using optical techniques, a self-flushing optical window operating at room temperature and requiring no external heating has been designed to prevent the collection of these condensates. The optical design allows the unobstructed transmittance of light into and out of several devices to which it is readily adopted.

    Direct synthesis of silicon nanowires, silica nanospheres, and wire-like nanosphere agglomerates (2000)

    Notes: Elevated temperature synthesis has been used to generate virtually defect free SiO2 sheathed crystalline silicon nanowires and silica (SiO2) nanospheres which can be agglomerated to wire-like configurations impregnated with crystalline silicon. The SiO2 passivated (sheathed) crystalline silicon nanowires, generated with a modified approach using a heated Si–SiO2 mix, with their axes parallel to 〈111〉 are found to be virtually defect free. Modifications to the system allow the simultaneous formation of SiO2 nanospheres (d∼10–30 nm) as virtually monodisperse gram quantity powders which form large surface area catalysts for the selective conversion of ethanol to acetaldehyde. © 2000 American Institute of Physics.

    Multiphoton ionization of Ag2: Assessment of a new excited electronic state and resolution of the Ag2 ionization potential (1995)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A previously unknown excited electronic state of Ag2 has been observed using mass selected resonant two photon ionization. The initial rovibrational level of this state observed via a forbidden transition near 46 870 cm−1 lies in near perfect double resonance with the lower energy A 1Σ+u(v'=3)←X 1Σ+g(v'=0) transition. The double resonance leads to an anomalously large single color ionization signal near the A(v'=3)←X(v‘=0) transition wavelength (426.7 nm). Symmetry selection rules allow an identification of the new state symmetry as 1g or 0+g [Hund's case (c)]. The presence of this state is demonstrated to have a significant impact on previous measurements of the ionization potential of Ag2. Two color resonant two photon ionization spectroscopy of the Ag2 A1Σ+u state is implemented using both excimer laser and Nd:YAG laser fourth harmonic ionization. The results of these experiments yield a new measurement of the ionization potential of Ag2, while demonstrating the importance of field ionization effects. © 1995 American Institute of Physics.

    High specific enthalpies from the photochemically induced isomerization: BOH↔HBO (1995)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The photochemical interconversion of BOH to the considerably more stable HBO isomer is evaluated. The BOH and HBO isomers, while differing considerably in energy, possess a significant barrier to interconversion on the ground 1A′ potential energy surface. However, by accessing the low-lying double minimum a 3A′ state, we define an interconversion pathway that facilitates the interconversion process, allowing a substantial energy release. Here, we calculate the potential surfaces for the X 1A′ and a 3A′ states of HBO–BOH and present limited evaluations for the b 3A″ and A 1A′ states. We outline means to distinguish the BOH and HBO isomers, following the progress of the isomerization process using optical, infrared, and mass spectrometric techniques. The energetics of this geometric isomerization process and the potential utilization of BOH as a storable high energy material are discussed. © 1995 American Institute of Physics.

    Confirmation of long-range collision complex stabilization through the controlled relaxation of high internal excitation (1995)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A series of controlled multiple collision chemiluminescent and laser induced fluorescent studies confirm the long-range collisional stabilization of high temperature group IIA dihalide complexes of some considerable spatial extent. The relaxation process demonstrates that the pseudocontinuum emissions observed under near single collision conditions [J. Chem. Phys. 102, 7425 (1995)] correspond to the overlap of a closely spaced, highly excited, rovibronic distribution. Controlled relaxation reveals the first vibrationally resolved electronic emission for the dihalides. The vibronic structure of the observed emission spectra correlates well with expectations based on the molecular electronic structure of the ground and low-lying electronic states of the dihalides. The vibronically resolved emission from the Sr+IClHe→SrICl* and mixed halogen Sr+Cl2, Br2→HeSrCl2*+SrBr2* reactions provides strong support for the formation of a collisionally stabilized dihalide complex. These results, correlated with near single collision studies, form a basis for the discussion of (1) the kinetics of formation of the dihalide complexes and (2) the implications of long-range collisional stabilization. Current theories may not accurately model these observations. Dihalide complex formation as it influences the energy partitioning to metal monohalide excited states may account for the discrepancies between those monohalide bond strengths determined by mass spectrometry and chemiluminescent techniques. © 1995 American Institute of Physics.
