Bromomethane (CH3Br) and iodomethane (CH3I) have been studied by binary (e,2e) coincidence spectroscopy at 1200 eV using non-coplanar symmetric kinematics. Separation energy spectra have been determined in the energy range up to 47 eV at azimuthal angles of 0° and 8° for CH3Br and 0°...
Resonant laser photodissociation of the cold parent ion followed by mass selective detection of the photofragment then leads to highly resolved vibronic spectra. We demonstrate the experimental capability using the Ã←X̃ 2Π12 transition of CH3I+ as an example. In addition, the unexpected ...
The molecular geometry is related to the electron domain geometry at the central atom, but it is not necessarily identical. Answer and Explanation: Bromine trifluoride is a covalent compound with a central bromine atom. Bromine (Br) on its own contains 7 valence electrons as a main group 7A...
Each central atom has an electron domain geometry and a molecular geometry. Both geometries are derived using VSEPR theory, based on the distribution of bonding and non-bonding valence electron pairs at the central atom. The important distinction is that non-bonding pairs are ignored as geometr...
We report cross sections for the trapping of 0–10 eV electrons by CH3Cl and CH3Br physisorbed onto a Kr covered Pt substrate, measured as a function of Kr film thickness and methyl halide concentration. The molecules stabilize electrons incident at the surface by the dis...

Answer to: Draw the Lewis structure for HCN. Determine the number of electron groups, the electron geometry, and the molecular shape. Is it polar...
ultrafast time scale in the range of as to ps. Emerging scientific innovations in many synchrotrons and FELs, with high brilliance and extremely high photon flux have wide opened a new domain of research in investigating many ultrafast processes. Information about what happens immediately after the...
the above geometry provides collinear propagation of both pulse replicas and thus constant phase difference across the beam profile. This enables to record phase-resolved autocorrelation signals with maximum contrast30. Soft X-ray interferometry requires high surface quality and position control of the re...
In PICTT, the metal plasmon serves as a light absorber, but strong interdomain coupling and mixing of the metal and semiconductor levels lead to a new plasmon decay pathway—the direct generation of an electron in the semiconductor and an electron– hole pair in the metal without the ...
