Abstract: | An experimental study has been undertaken to disclose the individual absorptionand lluorescence profiles of the two NH tautomers of 10-(4,6-dichloropyrimidin-5-yl)-5,15-dimesilylcorrole. The bands in the lluorescence spectra at room temperature and below have been assigned to the individual NH tautomers. The Stokes shift between the peaks of the 0-0 transition in absorbance and fluorescence at room temperature was found to be larger for the long wavelength T1 tautomer compared to the short wavelength T2 tautomer (270 cm{-1} vs. 165 cm{-1}, indicating that the T1 tautomer structure seems to be more flexible and undergoes slightly larger rearrangements in the excited singlet S[1] state as compared to the T2 tautomer. |
