abstract = {Photon-by-photon analysis tools for diffusion-based
single-molecule Förster resonance energy transfer (smFRET)
experiments often describe protein dynamics with Markov
models. However, FRET efficiencies are only projections of
the conformational space such that the measured dynamics can
appear non-Markovian. Model-free methods to quantify FRET
efficiency fluctuations would be desirable in this case.
Here, we present such an approach. We determine FRET
efficiency correlation functions free of artifacts from the
finite length of photon trajectories or the diffusion of
molecules through the confocal volume. We show that these
functions capture the dynamics of proteins from nano- to
milliseconds both in simulation and experiment, which
provides a rigorous validation of current model-based
analysis approaches.},
