The geometries of one-electron reduced/oxidized species ([TOP]/[VOP]) of vanadyl porphyrin (VOP) have been calculated with PBE1PBE method. The results show that for both [VOP]− and [VOP] the ground states are triplet, in which one of the two unpaired electron occupies the dxy orbital of the V atom while the other occupies the π-orbital of porphyrin ring. Thus both [VOP]− and [VOP] can be consid...

We present a density functional theory (DFT) calculation in the generalized gradient approximation to study the possibility for the existence of Jahn-Teller (JT) or pseudo Jahn-Teller (PJT) type local distortions in the La-Ba-Cu-O superconducting system. The analysis is based on the calculation and correspondingly group theory classification of the electronic ground state of the CuO6 −10 elonga...

The leader operators of the (d + 1)-dimensional relativistic rotating oscillators Abstract The main pairs of leader operators of the quantum models of rela-tivistic rotating oscillators in arbitrary dimensions are derived. To this end one exploits the fact that these models generate Pöschl-Teller radial problems with remarkable properties of supersymmetry and shape invariance.

Jahn-Teller theorem, proposed in 1937, predicts a distortional instability for a molecule that has symmetry based degenerate electronic states. In 1939 Krishnan emphasized the importance of this theorem for the arrangement of water molecules around the transition metal or rare earth ions in aqueous solutions and hydrated saltes, in a short and interesting paper published in Nature by pointing o...

for an Invited Paper for the MAR07 Meeting of The American Physical Society Anti-Jahn-Teller effect and d-wave phonon mechanism in cuprates HIROSHI KAMIMURA, Tokyo University of Science Undoped cuprates are Jahn-Teller (JT) Materials [1] and Mott AF insulators [2]. When holes are doped, the octahedrons or pyramids elongated by the JT effect shrink. We call such distortion against the JT effect ...

Objectives The German socio-demographic estimation scale was developed by Jahn et al. (1) to quickly predict premorbid global cognitive functioning in patients. So far, it has been validated in healthy adults and has shown a good correlation with the full and verbal IQ of the Wechsler Adult Intelligence Scale (WAIS) in this group. However, there are no data regarding its use as a bedside test i...

The C4H4 isomer cyclobutadiene (CBD) is the prime model for antiaromaticity and thus a molecule of considerable interest in chemistry. Because it highly reactive, can only be studied under isolated conditions. Its electronic structure characterized by pseudo-Jahn–Teller effect neutral E ⊗ β Jahn–Teller cation. As result, recording photoelectron spectra as well describing them theoretically has ...
