Electronic structure of coumarins
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2002The electronic structure of coumarin derivatives has been investigated by a combination of UV photoelectron spectra (UPS), semi-empirical MO calculations and comparison with the spectra of related coumarins. The influence of substituents on the S0 and S1 electronic states energies is discussed.

Electronic Structure of the Nucleobases
The Journal of Physical Chemistry B, 2005We present a comparison between experimental and calculated soft X-ray spectra of DNA's nucleobases, adenine (A), guanine (G), cytosine (C), and thymine (T) using X-ray absorption spectroscopy (XAS) and soft X-ray emission spectroscopy (XES). Spectra of the 1s thresholds of carbon, nitrogen, and oxygen give a complete picture of the occupied and ...

Physical Review B, 1991
The electronic structure of MnO has been investigated using high-energy (x-ray photoelectron and bremsstrahlung-isochromat) spectroscopies. An experimental gap of 3.9 eV is found. By comparing the experimental results to a configuration-interaction cluster model, values for the different parameters in a model Hamiltonian are found [U=8.5 eV, DELTA = 8 ...

Optical Properties and Electronic Structure of Amorphous Germanium
1966, 1966The optical constants of amorphous Ge are determined for the photon energies from 0.08 to 1.6 eV. From 0.08 to 0.5 eV, the absorption is due to k-conserving transitions of holes between the valence bands as in p-type crystals; the spin-orbit splitting is

Electronic structure of schwarzite [PDF]
Physical Review B, 1992 We examine the electronic structure and total energies of schwarzites (negative-curvature analogs of the fullerenes). These structures have curvature induced via the presence of seven- or eight-membered rings. Ab initio dynamical relaxations reveal that these structures are closer in energy to graphite than are the fullerenes.

Materials Science Forum, 1994
This review presents some of the progress which has been made in the study of electronic structure of some metals, alloys and oxides. Rather than giving a complete presentation, we develop some subjects which may be representative of the development since ICPA-9.

Journal of Physics: Condensed Matter, 1998
The electronic structure of and corresponding x-ray photoemission spectra (XPS) are presented. The band structure is calculated by the spin-polarized tight binding linear muffin tin orbital (TB LMTO) method. The XPS valence bands are compared with the calculated electronic density of states.
