چکیده

2014 The orbital chemical shift of N.M.R., which measures the weight of non-s states in the chemical bond, can be related directly to the ionicity for tellurium compounds. In a molecular picture of the solid neglecting d states, the shift is a parabolic function of the number of p-electrons in the valence band. This number depends simply on the ionicity for tellurium bonds and can be modified by change in the local symmetry, especially by amorphization.

Quasirelativistic study of 125Te nuclear magnetic shielding constants and chemical shifts

Calculations for 125Te magnetic shielding constants and chemical shifts were carried out using a quasirelativistic Hamiltonian including the spin-free relativistic, oneand two-electron spin–orbit, and relativistic magnetic interaction terms. For the tellurium-containing series Te(CH3)2, TeH2, TeF6, Te(CH3)4, and Te(CH3)2Cl2, the relativistic effects amounted to as much as 1300 ppm and were very...

1H-n.m.r. study of the solution properties and secondary structure of neurotoxin III from the sea anemone Anemonia sulcata.

The solution properties, secondary structure and global fold of the 27-residue polypeptide neurotoxin III (ATX III), from the sea anemone Anemonia sulcata, have been investigated using high-resolution 1H-n.m.r. spectroscopy. Studies of the concentration dependence of the n.m.r. spectrum indicate that the molecule self-associates in the millimolar concentration range useable for n.m.r. analysis,...

 Studies of phenomena such as charge, orbital and spin ordering in manganite has attracted much interest in recent years. These studies have been possible from an experimental point of view by the third generation synchrotron sources. X-ray with high flux density, tunable energy and polarization can be produced in synchrotron sources. Experiments have shown a resonant in peak intensity originat...

Calculations of NMR chemical shifts with APW-based methods

We present a full potential, all electron augmented plane wave (APW) implementation of first-principles calculations of NMR chemical shifts. In order to obtain the induced current we follow a perturbation approach [Pickard and Mauri, Phys. Rev. B 63, 245101 (2001)] and extended the common APW + local orbital (LO) basis by several LOs at higher energies. The calculated all-electron current is re...

Natural Bond Orbital (NBO) Study of (5H-tetrazol-1-yl)(triphenylphosphine)gold [Au(tetz)(PPh3)]

In this research work, we studied theoretically the structural properties of (5H-tetrazol-1-yl)(triphenylphosphine)gold or [Au(tetz)(PPh3)] by density functional theory (DFT) method at LANL2DZ level. All calculations were performed at 298.15 K and 1 atmosphere. Firstly, the bond lengths, bond angles, dihedral angles and natural charge density on atoms of the compound were calculated. The depend...
