Picosecond absorption spectroscopy has been used to study the rotational reorientation of cresyi violet in methanol solutions containing poly(ethylene oxide). The increase in the rotational reorientation time with increasing polymer concentration can be attributed to the short-range hydrodynamic interactions between the dye and entangled polymer chains.
