This paper illustrates the application of group theory to a quantum-mechanical three-dimensional quartic anharmonic oscillator with Oh symmetry. It is shown that group theory predicts the degeneracy of the energy levels ...

We show that a system of four particles in a one-dimensional box with a two-particle harmonic interaction can by described by means of the symmetry point group Oh. Group theory proves useful for the discussion of both the ...

A symmetry adapted formalism to evaluate the vibronic intensities induced by the ungerade vibrational modes in centrosymmetric coordination compounds of the rare earths is put forward and applied to several selected ...

The Buckminster fullerene C-60 molecule was analyzed from the point of view of global and local reactivity. In particular, the dual descriptor-a local reactivity descriptor derived from conceptual density functional ...

We have investigated the spin-spin coupling constants (SSCC's) of diborane(4) and diborane(6), their Li-doped counterparts, and the dimerization of diborane(6), using the second order polarization propagator approximation ...

Heliconius butterflies are an excellent example of Müllerian mimicry, where phylogenetically distant species converge to nearly identical wing phenotype when occurring in sympatry. However, few studies have comprehensively ...
