Spin atomic

Eq. (21) is an example of such proper parametrization. The dynamical spin orbitals are expressed in tenns of atomic spin orbitals centered on the various nuclei... 

All of the geometry optimizations for acetyl radical produce similar structures. Here are the predicted spin densities (labeled Total atomic spin densities in the Gaussian output) ... 

Since a considerable amount of review articles on both theoretical frameworks and calculated results have been reported[15-25], the main objective of the present study is placed on the comparisons with experimental results. The organization of the present report is as follows In the next section, for the sake of completeness, a brief theoretical description of the PPM is summarized from the previous articles. In the third section, disorder-LIq transition is focused and visualized atomic (spin) configuration is compared with recent high resolution electron micrograph. In the fourth section, ordering relaxation...

The change in the Mossbauer spectrum of an antiferromagnetic material produced by an external field is considerably less dramatic than for a ferromagnetic material. Since there is no net moment per unit cell for Hext to interact with, as a first approximation in a randomly oriented antiferromagnet, Hext will increase H in about half the atoms and decrease H in the others, depending on the orientation of an individual atomic spin. The net result is to broaden the lines of the Mossbauer... 

The Wlc total atomization energy at 0 K of aniline, 1468.7 kcal/mol, is in satisfying agreement with the value obtained from heats of formation in the NIST WebBook 39), 1467.7 0.7 kcal/mol. (Most of the uncertainty derives from the heat of vaporization of graphite.) The various contributions to this result are (in kcal/mol) SCF limit 1144.4, valence CCSD correlation energy limit 359.0, connected triple excitations 31.7, inner shell correlation 7.6, scalar relativistic effects -1.2, atomic spin-orbit coupling -0.5 kcal/mol. Extrapolations account for 0.6, 12.1, and 2.5 kcal/mol, respectively, out of the three first contributions. 

The metallic part would vanish, of coimse, for empty or filled bands, and in the case of strong localization ((Ex — Cx) = 0). To the first term, a spin polarized form may also be given as for metals and a further source of vanishing of this term may be identified when full atomic spin polarization is achieved. 

For actinide atoms E is of the order of 60.000 Ryds. If the cohesive energy of a solid is required it is necessary first to compute the total energy of the atom, spin polarizing the...
