✦ Synopsis

The absorption spectra of the TCNB-toluene complex in the fluorescent state at 4.2"K were observed. On the basis of the results of excited singlet-singlet absorption spectra of some TCNB complexes at various temperatures, available fluorescence spectral data were re-interpreted. Instead of the model of so-called structural change, an alternative explanation in terms of: the triple complex (DlA-) in the excited state is proposed.
