In a recent paper (J Fluoresc (2011) 21:1547–1557) a temperature induced modulation of Coumarin 153 (C153) fluorescence lifetime and quantum yield for the probe dissolved in the polar, nonspecifically interacting 1-chloropropane was reported. This modulation was also observed in temperature dependencies of the radiative and nonradiative rates. Here, we show that the modulation is also observed in...
We report a study of the thermochromic shifts observed for coumarin 153 (C153) emission spectra in several selected chloroalkanes and several solvents potentially specifically interacting with the probe. It has been found that the shifts observed in five 1-chloroalkanes can be successfully predicted using the McRae molecular interaction model [E.G. McRae, J. Phys. Chem. 61 (1957) 562]. However, the...
