Do fluorescence and transient absorption probe the same intramolecularcharge transfer state of 4-(dimethylamino)benzonitrile?

摘要

We present here the results of time-resolved absorption and emission experiments for4-(dimethylamino)benzonitrile in solution, which suggest that the fluorescent intramolecular chargetransfer (ICT) state may differ from the twisted ICT (TICT) state observed in transientabsorption.
