Presents a synchrotron radiation photoemission study of the upper-valence-band states of four ZrSe3-structure compounds: ZrS3, ZrSe3, ZrTe3 and HfSe3. The sulphide and selenide spectra exhibit a charac ...
Bromide promoted decompn. of tert-Bu bromide in the presence of triphenylphosphine gives, besides isobutene, hydrogen(triphenyl)phosphonium bromide. When heated to approx. 150 DegC in the presence of xylene, the latter salt liberates hydrogen bromide which ...
We investigated the adsorption properties of methanol and ethanol on Si(111)2 x 1 as a function of temperature in the range 80-300 K by means of synchrotron radiation photoemission of core and valence levels. A physisorbed state is characterized at 80 K, w ...
Excitation of the A(3ss) Rydberg state of NO trapped in an H2 crystal leads to the electronic bubble formation around the NO impurity, resulting in an increase of 0.9 .ANG. of the ground state cage radius. Its dynamics was followed in real-time by femtosec ...
A model based on fluid dynamics is proposed, which describes the dynamics of a photoinduced spherical deformation in solid hydrogen. The dynamics is driven by femtosecond excitation of the lowest A(3ss) Rydberg state of NO trapped in an H2 crystal, leading ...
Rydberg series obsd. in the excitation spectra of Cl and H atoms isolated in the rare gas (Rg) crystals Kr and Xe are assocd. with the charge transfer species Cl-Rg+ and H-Rg+. The progressions originate from hole states of Rg+ which converge to the top of ...
We report on the ultrafast dynamics of electronic bubble formation following excitation of the A 3ss Rydberg state of the NO mol. trapped in argon and hydrogen matrixes. The study is carried out by femtosecond fluorescence depletion expts. Apparently in hy ...
The effects of hydrogen diffusion on p-n GaAs junctions have been studied by electron beam induced current (EBIC) and cathodoluminescence (CL) at room temperature. Hydrogen passivates both the acceptors in the p-side of the junction and the donors in the n ...
The medium response of solid hydrogens to an impulsive perturbation has been studied using Rydberg excitation of an NO impurity. This leads to formation of an "electronic" bubble which corresponds to a cage radius increment of about 25%. The process has ...
In this paper we demonstrate that six molecules of a functionalized isophthalic acid derivative form a cyclic aggregate stabilized by a network of 12 hydrogen bonds. The structure and stability of the aggregate were studied by X-ray crystallography, vapor ...
