The ratio of peak III to peak I intensities of the so-called III and I fluorescence bands of pyrene increases dramatically when cupric ions are used as quenchers for pyrene emission in sodium dodecyl sulfate micelles. These results indicate a decrease in the polarity sensed by the probe when its lif
