• The probabilities P of the energy transfer by dipole-dipole interaction from excited pyrene to non-excited perylene in n-hexane were measured by a pulse method. The value of P was found to be approximately proportional to the relative diffusion coefficient D of both molecules above the value D of 3.5×10^<-5> cm^2/sec and to D^<3/4> below that value of D. When D is large both molecules migrate so rapidly that they collide with each other before the excited donor transfers its energy to the acceptor by dipole-dipole interaction. Meanwhile, if D is small, the energy transfer by dipole-dipole interaction takes place from the donor to the distant acceptor before their collision. The experimental results were well analyzed by Yokota and Tanimoto's calculation.
