Abstract
Anomalies in the fluorescence spectra of dual fluorescence molecules explained? A comparison of the time-resolved I R absorption of the C≡N band of photoexcited 4-dimethylaminobenzonitrile in MeCN and MeOH provides the first direct observation of the formation of a hydrogen-bonded intramolecular charge-transfer (ICT) state in MeOH and its coexistence with a "free" ICT state (see picture). The so-called dual fluorescence will be triple, not dual.
