We have studied experimentally the dipole orientation and reorientation dynamics of single dye molecules at room temperature. The dipole rotation of individual dye molecules which are physisorbed to glass and embedded in spin-cast polymer films is measured with the confocal scanning optical microscopy and the method of fluorescence polarization analysis, the probability of reorientation of single molecules found to be about 5%—9% when embedded in polymer, and about 26% when absorbed to glass by using the statistic analysis. It is found the quantum jumps for molecule dipole reorientation are distributed in several different polarization states by measuring the polarization degree of fluorescent photons.
