Double-resonance overtone photofragment spectroscopy of trans-HONO. I. Spectroscopy and intramolecular dynamics

Using the technique of double-resonance overtone photofragment spectroscopy (DROPS), we have measured rotationally resolved vibrational overtone transitions to the previously unobserved 5v(1), 6v(1), and 7v(1) levels of gas-phase trans-nitrous acid (HONO) ...

Direct observation of new transitions in the absorption spectra of a V-groove quantum wire waveguide

Elyahou Kapon, Alok Rudra, Marc-André Dupertuis, Daniel Oberli, Klaus Leifer

We report on the direct absorption measurement of the polarization selection rules in a V-groove QWR waveguide. Attenuation measurements in a 1 mm long waveguide were performed from 10 K up to room temperature. These measurements yielded the QWR DOS select ...

Spectromicroscopy of boron in human glioblastomas following administration of Na2B12H11SH

Giorgio Margaritondo, Luca Perfetti

Boron neutron capture therapy (BNCT) is an experimental, binary treatment far brain cancer which requires as the first step that tumor tissue is targeted with a boron-10 containing compound. Subsequent exposure to a thermal neutron flux results in destruct ...

The phases of CS3Bi2I9 between RT and 190 K

Gervais Chapuis, Alla Arakcheeva

The structure of Cs3Bi2I9 has been refined to R = 0.0165 on the basis of X-ray diffraction measurements at T = 290 K (STOE IPDS diffractometer; MoKalpha-radiation; 296 nonequivalent reflection with I > 2 sigma(I)). The absorption correction was accounted f ...

Strain-amplitude-dependent mechanical loss at intermediate temperatures in a Ni-3(Al, Ta) single crystal

Robert Schaller, Nadine Baluc, Joël Bonneville

Dislocation dynamics in a Ni-3(Al, Ta) single-crystal alloy have been studied by means of mechanical spectroscopy at intermediate temperatures, that is in the temperature range of the flow stress anomaly. The mechanical loss of specimens predeformed at 300 ...

Spectroscopy and energy relaxation processes of Hg2 and Hg in solid Ne

Majed Chergui

The spectroscopy of Hg2 mols. in Ne matrixes was studied using absorption, excitation and emission spectroscopy. Emission spectra show fluorescence from the lowest A0g+ and the B1g states, sepd. by .apprx.1500 cm-1, to the ground state X0+g. Their excitati ...

The development and application of imaging EXAFS spectromicroscopy

Giorgio Margaritondo, Helmuth Berger

The capability to perform absorption spectroscopy with hard x-rays was added to the synchrotron imaging spectromicroscopy technique. We present several successful test cases. First, the EXAFS (extended x-ray absorption fine structure) analysis was implemen ...

[OH(X)] measurements by resonant absorption spectroscopy in a high pulse voltage triggered Dielectric Barrier Discharge

Cyrille Hibert

Good understanding of the different phases of involved plasma-chemistry is essential for the development of non thermal plasma technologies for pollution control. These techniques are often based on the production of radicals from dissociation parent gases ...

Photodissociation detection of microwave transitions in highly excited vibrational states

Thomas Rizzo

This paper describes a new spectroscopic technique which uses photodissociation to detect pure rotational transitions in highly excited vibrational energy levels of the ground electronic state. This method has initially been applied to the (HOCl)-Cl-35 mol ...

Low temperature scanning tunneling microscopy and spectroscopy in ultra-high-vacuum and high magnetic fields

We have developed an ultra-stable low temperature scanning tunneling microscope (LTSTM) for application in atomic scale spectroscopy and atom manipulation experiments. The design is based on the Besocke type microscope allowing the installation of the LTST ...
