A simple molecular orbital theoretical treatment of the sigma-pi interaction caused by chemical reactions of planar-conjugated systems has been developed. The problem of the streoselection of the two alternative directions of configuration altering due to the hybridization change at the centers of ...

The scattering lengths of the pi Sigma systems are key quantities in understanding the structure of the Lambda(1405) resonance and the subthreshold extrapolation of the barK N interaction. We demonstrate that the pi Sigma scattering lengths can be extracted from the threshold cusp phenomena in the ...

The authors report a global potential energy surface for the ground electronic state of HO2(X (2)A(')), which improves upon the XXZLG potential [Xu and , J. Chem. Phys. 122, 244305 (2005)] with additional high-level ab initio points for the long-range interaction potential in the O...
Radiative lifetimes for the A-X, B-X, and B-A electronic transitions in CN are calculated as a function of the upper vibrational level using complete active space self-consistent field configuration interaction electronic wave functions. All molecular orbitals which can be formed from the atomic ...
Since a four-fermion interaction is a dimension six operator, the NJL model is not renormalizable in four space-time dimensions. To obtain finite expressions we must regularize the theory. In such a non-renormalizable model most of the physical quantities depend on the regularization method ...
