Abstract
Fluorescence anisotropy decays for perylene in squalane and methylcycl ohexane (MCH) show marked departures from the behavior predicted by hy drodynamic theory. Two exponentials are observed; both their extent an d their rate show different dependences on temperature. In contrast, 1 ,6-diphenylhexatriene in MCH shows a single-exponential decay rate pro portional to eta/T.
