    Sieve cells in Phloem of a middle devonian progymnosperm (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-09-28
    Description: Phloem tissue from a Middle Devonian member of the Aneurophytales (Progymnospermopsida) is described. This may be the oldest firm evidence of conducting elements of the phloem, extending our knowledge of this tissue back some 35 million years. The discovery indicates a close phylogenetic relation between progymnosperms and gymnosperms and provides a basis for investigating patterns of specialization in the phloem of these groups of plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wight, D C -- Beck, C B -- New York, N.Y. -- Science. 1984 Sep 28;225(4669):1469-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17770075" target="_blank"〉PubMed〈/a〉

    Laser multiphoton dissociation–multiphoton ionization and photoelectron spectroscopy of Fe(C5H5)2, Co(C5H5)2, and Ni(C5H5)2 (1992)

    Notes: Laser multiphoton dissociation–resonance-enhanced multiphoton ionization (MPD–REMPI) and time-of-flight photoelectron spectra (TOF-PES) of Fe(C5H5)2, Co(C5H5)2, and Ni(C5H5)2 have been obtained in the range 380–390 nm, and the MPD–REMPI of Fe(C5H5)2 and Co(C5H5)2 have been obtained in the range 445–455 nm. The only ions produced by the pulsed dye laser are Fe+, Co+, and Ni+. Transitions observed in the MPD–REMPI spectra are assigned to resonant states of the neutral atoms. Final states of the atomic ions are determined from the TOF-PES spectra. For Ni and Co, there appears to be a propensity for core preservation of the resonant state upon ionization if the resonant state has an electron configuration with an electron in a d-type Rydberg orbital. For Fe, no such propensity is observed.

    Laser multiphoton ionization and photoelectron spectroscopy of Co(CO)3NO and Fe(CO)5 (1990)

The only ions produced by the pulsed dye laser are Co+ and Fe+. Transitions observed in the MPD-REMPI spectra are assigned to resonant states of the neutral atoms. Final states of the atomic ions are determined from the TOF-PES spectra. The multiphoton dissociation process produces metal atoms in a broad distribution of states, ranging in energies up to 33 000 cm−1 for Co, and 32 000 cm−1 for Fe. The most intense REMPI lines are associated with low-lying electronic states (〈8500 cm−1 for Fe and Co). By tuning the laser to appropriate wavelengths, neutral metal atoms in selected electronic states may be ionized. At most laser wavelengths, the atomic metal ions are formed in a distribution of states, only some of which are consistent with preservation of the core configuration of the Rydberg intermediate in the ionization step. An exception appears for ionization of Co atoms via 4d Rydberg intermediate states.

    Free radical chain reactions of chlorine with cyclobutane in the solid state: Evidence for radical migration via H atom transfer (1988)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The laser-initiated reaction of chlorine with cyclobutane, deposited as a thin amorphous film at 77 K, is found to produce exclusively chlorocyclobutane and HC1 via a free radical chain mechanism. The reactions are initiated by pulsed laser photolysis of molecular chlorine at 308 nm. Product formation is monitored by Fourier transform infrared absorption spectroscopy. The quantum yield for reaction increases from 1.1±0.3 in an equimolar mixture to a yield of 7.4±0.8 for mixtures rich in cyclobutane. These results are consistent with a reaction mechanism which involves the transfer of a hydrogen atom from cyclobutane to cyclobutyl radical, permitting the radical site to propagate freely in the solid.

    Photofragment spectroscopy of cobalt tricarbonylnitrosyl and its trialkylphosphine derivatives (1989)

    Notes: The photodissociation of gaseous Co(CO)3(NO) and Co(CO)2(NO)(PX3), where X=CH3, C2H5, n-C3H7, and n-C4H9 has been investigated near 225 nm by state-selective multiphoton ionization detection of nitric oxide fragments. The observed NO photofragment rotational distributions in v=0 are approximately Boltzmann, and the characteristic temperature decreases with increasing size of the phosphine ligand. The yield of photofragments appearing within the 10 ns detection time scale also decreases with increasing molecular size. An analogous effect is observed for the v=1/v=0 vibrational population ratio of the NO photoproducts. These results show that intramolecular energy transfer is fast compared with scission of the Co–NO bond. A dissociation model is proposed involving initial loss of CO followed by loss of other ligands via an RRKM-like process.

    Inhomogeneous broadening of infrared and Raman spectral bands of amorphous and polycrystalline thin films (1993)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Infrared and Raman spectroscopy are used to examine effects of solid structure on vibrational line shapes in thin solid films of CO2 and N2O prepared by vapor deposition. A new method is described for forming films consisting of weakly-interacting microcrystals by deposition of the solute in an argon matrix followed by complete evaporation of the argon. The infrared absorption bands of these films exhibit inhomogeneous spectral broadening in the range between the transverse and longitudinal frequencies of the bulk crystal. The origin of this broadening is shown to be the dependence of vibrational frequencies on size and shape of the microcrystals due to long-range dipole interactions. In contrast, the spectra of polycrystalline films formed by direct vapor deposition are the same as for single crystals because the long-range dipole interactions effectively couple vibrational motions across the grain boundaries. An analysis shows that inhomogenously broadened spectra are obtained whenever the separation between the individual crystal grains is comparable to or greater than their dimensions.

    Pulsed optically pumped polarized H− ion source development : Proceedings of the 6th international conference on ion sources (1996)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Results are presented of a pulsed optically pumped polarized H− ion source development for high energy accelerators. An atomic hydrogen beam intensity of 2×1018 atoms/s within the polarizer acceptance was obtained with an atomic H injector at BINP. A pulsed polarized H− ion current of about 10–20 mA should be obtainable using this injector. Limitations on beam characteristics due to space charge were studied. A polarization scheme to avoid space charge limitations is considered, in which charge exchange and spin exchange are combined. © 1996 American Institute of Physics.

    Notes: The TRIUMF dc optically pumped polarized H− ion source (OPPIS) produces a 200 μA dc H− current at 85% polarization within a normalized emittance (90%) of 0.8 π mm mrad, for operation at the TRIUMF cyclotron. As a result of development of the electron cyclotron resonance primary proton source, a 1.6 mA dc polarized H− current is produced within a normalized emittance of 2 π mm mrad, suitable for high energy accelerators. The OPPIS has also been developed for use in a parity nonconservation experiment which has very severe limits on permissible helicity- correlated changes in beam current and energy. © 1996 American Institute of Physics.
