4f-4f intensities of the Tm3+ ions in fluoroindate glasses: the influence of third-order effects through odd intensity parameters
(Elsevier B.V., 1998-07-24)
In this work an analysis of the phenomenological Omega(lambda) intensity parameters for the Tm3+ ion in fluoroindate glass is made using the standard Judd-Ofelt theory, and a modified oscillator strength taking into account ...
Theoretical study on electronic spectra and interaction in [Au3]-L-[Au3] (L 0 C6F6,Ag+) complexes
(Springer, 2013)
The electronic structure and spectroscopic properties
of [Au3(μ-C(OEt) 0 NC6H4CH3)3]n-(C6F6)m and
[Au3(μ-C2,N3-bzim)3]n-(Ag+)m were studied at the B3LYP,
PBE and TPSS levels. The interaction between the [Au3]
cluster ...
Theoretical Study of the Absorption Spectra of Photosynthetic Pigments
(Sociedade Brasileira de FísicaÁguas de Lindóia, 2013-05-13)
The first stage of the photosynthetic process is the extraordinary efficiency of sunlight absorption in the visible region [1]. This region corresponds to the maximum of the spectral radiance of the solar emission. The ...
Theoretical study of electronic spectra of [Pt3(μ-CO) 3(CO)3]n-2 (n = 3-5) complexes
(2009)
The platinum-platinum attraction and the spectroscopic properties of [Pt3(μ-CO)3(CO)3]n-2 (n = 3-5) were studied at the PBE level. Theoretical calculations are in agreement with experimental geometries. The absorption ...
Analysis of electronic structure and X-ray absorption and emission spectra in MgO within the FP-LAPW method
(Sciencedomain international, 2018-10-05)
In this work we calculated MgO ab initio X-ray Absorption and Emission spectra using the Full Potential Linearized Augmented Plane Wave method within the Density Functional Theory formalism. The X-ray Absorption and Emission ...
