Photoelectron spectroscopy of nickel-benzene cluster anions.
(Nickel)(n)(benzene)(m) (-) cluster anions were studied by both mass spectrometry and anion photoelectron spectroscopy. Only Ni(n)(Bz)(m) (-) species for which n > or =m were observed in the mass spectra. No single-nickel Ni(1)(Bz)(m) (-) species were seen. Adiabatic electron affinities, vertical detachment energies, and second transition energies were determined for (n,m)=(2,1), (2,2), (3,1), ...
متن کاملPhotoelectron Spectroscopy of Alkali Metal Cluster Anions
ABSTRACf. We present the photoelectron (photodetacment) spectra of K2:-19 recorded using 2.540 eV photons. These spectra are highly structured, providing a wealth of information about the electronic structure of alkali metal clusters, including adiabatic electron affinities and electronic spliuings for each size. Spectral assignments have been made with guidance from theory. For the smaller clu...
متن کاملPhotoelectron spectroscopy of chromium-doped silicon cluster anions.
The photoelectron spectra of chromium-doped silicon cluster anions, CrSi-(n), were measured over the size range, n=8-12. Their vertical detachment energies were measured to be 2.71, 2.88, 2.87, 2.95, and 3.18 eV, respectively. Our results support theoretical calculations by Khanna, Rao, and Jena [Phys. Rev. Lett. 89, 016803 (2002)] which found CrSi12 to be an enhanced stability (magic) cluster ...
متن کاملPhotoelectron spectroscopy of boron aluminum hydride cluster anions.
Boron aluminum hydride clusters are studied through a synergetic combination of anion photoelectron spectroscopy and density functional theory based calculations. Boron aluminum hydride cluster anions, BxAlyHz(-), were generated in a pulsed arc cluster ionization source and identified by time-of-flight mass spectrometry. After mass selection, their photoelectron spectra were measured by a magne...
متن کاملAluminum cluster anions: Photoelectron spectroscopy and ab initio simulations
Atomic structures and geometries, electronic structure, and temperature-dependent photoelectron spectra of AlN 2 (N5192102) clusters are studied both theoretically via ab initio local-density-functional simulations, and experimentally with high-resolution measurements. The use of a theoretically well-defined energy shift in conjunction with a generalized Koopmans’ theorem enables direct compari...
