Rotational Dynamics of PRODAN in _-CD
The best rotational model for the experimental data involved two separate rotating spheres each assigned to one of the fluorescence lifetimes.
The PRODAN / _-CD complex has a rotational correlation time of about 1 ns. As the PRODAN binds to the CD, the volume of the complex increases resulting in a longer (slower) Rotational Correlation Time (RCT). The Debye-Stokes rotational model agrees well w
