Electron-Nucleon Dynamics Investigations on Small Molecular Systems
Frank Hagelberg
The dynamics of molecular and cluster systems has been treated in the past predominantly within the confines of the adiabatic approximation. While this approach is adequate for most situations and phenomena of interest, it fails for problems which involve strong coupling bet- ween nuclear and electronic degrees of freedom. For in- stance, molecular motion in the vicinity of a Jahn-Teller instability is usually not well accounted for by the adiabatic approximation. In the present talk, the basics of the recent 'Electron Nucleon Dynamics' (END) Theory will be briefly outlined. This theory allows for explicit time dependence of the electronic wavefunction and is thus free from the restric- tions of the adiabatic approximation. Applications of the END theory to three- and fouratomic Jahn-Teller systems will be discussed.
