Single‐molecule fluorescence dynamics in polystyrene are statistically analyzed to reveal correlations between fluctuations in emission wavelength λ 0 and intensity I 0 (see picture). These correlations were found to depend on the mean emission wavelength of the single molecules, which proves synchronous shifts of the absorption and fluorescence single‐molecule spectra.
