Hi

There are numerous examples of TDDFT producing unrealistic and
unexpected results on various systems.  The system itselt should be well
studied both experimentally and theoretically before extracting deep
information from TDDFT results.

Molecular Physics, Vol. 103, No. 6, 2005, 1057.

should provide one example of the analysis of TDDFT performance.

Regards

Tarmo
