Zusammenfassung der Projektergebnisse

The current project was supported by the DFG in a consortium with the French ANR. We had asked for travelling money and for a postdoctoral position on the German side. All the main objectives of the project have been achieved successfully: the description of the π-to-π∗ photo-excitation of ethene and the development of a new program to generate kinetic energy operators.
