Imaging molecular geometry with electron momentum spectroscopy
Electron momentum spectroscopy is a unique tool for imaging orbital-specific electron density of molecule in momentum space. However, the molecular geometry information is usually veiled due to the single-centered character of momentum space wavefunction of molecular orbital (MO). Here we demonstrate the retrieval of interatomic distances from the multicenter interference effect revealed in the...
متن کاملSome perspectives in electron momentum spectroscopy experiments
The basic challenges of electron momentum spectroscopy (EMS) as it has guided our research efforts at Carleton University are outlined. These challenges are: (a) Are the spectroscopic factors obtained in EMS equivalent to the spectroscopic factors observed in photoelectron spectroscopy? (b) Can experimental momentum profiles be related to the chemical reactivity of complex molecular systems? (c...
متن کاملRecent Advances in Electron Momentum Spectroscopy *
The flexibility of the (e, 2e) technique or "electron momentum spectroscopy" (EMS) in obtaining information on the electronic structure of atoms, molecules, and solids is demonstrated. Highresolution EMS measurements for argon, including the first measurements of momentum profiles belonging to the 2 P° and D-manifolds, are used to demonstrate the technique for atomic targets. The d-wave transit...
متن کاملRecoil-Ion and Electron Momentum Spectroscopy: Reaction-Microscopes
Recoil-ion and electron momentum spectroscopy is a rapidly developing technique that allows one to measure the vector momenta of several ions and electrons resulting from atomic or molecular fragmentation. In a unique combination, large solid angles close to π 4 and superior momentum resolutions around a few percent of an atomic unit ( . .u a ) are typically reached in state-of-the art machines...
متن کاملInvestigation of valence orbitals of propene by electron momentum spectroscopy.
The binding energy spectra and momentum distributions of all valence orbitals of propene were studied by electron momentum spectroscopy (EMS) as well as Hartree-Fock and density functional theoretical calculations. The experiment was carried out at impact energies of 1200 eV and 600 eV on the state-of-the-art EMS spectrometer developed at Tsinghua University recently. The experimental momentum ...
