The rotational motions of various acridine dyes bound to DNA were investigated by the measurements of nanosecond fluorescence anisotropy. It was found that the total decay of fluorescence is a single exponential, whereas the decay of fluorescence anisotropy is a sum of an exponential function and a constant. The apparent values of the rotational relaxation time of the complexes calculated from anisotropy data range from 21 to 31 ns. The results are discussed by comparing with those obtained from the measurements of steady-state fluorescence depolarization.
