Extended Data Figure 2: Photon trajectory and kinetics models.
From: Single-molecule fluorescence probes dynamics of barrier crossing
a, The definition of photon indices and time interval of a photon trajectory with a folding transition. b, c, Photon trajectories were analysed using the two-state model to determine kinetics parameters (b) or the three-state model to determine the average transition path times (tTP = 1/2kS) (c).
