✦ Synopsis


The excited singlet-singlet absorption spectra of s-tetracyaobenzene (TCNB) complexes with toluene and benzene were observed. The spectra were obtnined using the re-absorption of the CT fluorescence by the fluorescent EDA complexes produced densely by means of the excitation with a giant pulse Iaser. The non-exponential decay characteristics, at the wavelengths of re-absorption, agreed quite well with theoretical expectations.
