Fitting parameters for polyproline-AF 488-Atto 740.

Parameter	Value
f_T1 ^a	0.07
τ_T1 (μs) ^a	10
f_T2 ^a	0.06
τ_T2(μs) ^a	6.7
N_tot	7.81
τ_d(μs)	188
E₁ ^b	0.89

Triplet parameters: f_T1: fraction for donor fluorophore; τ_T1: triplet correlation time for donor fluorophore; . f_T2: fraction for acceptor fluorophore; τ_T2: triplet correlation time for acceptor fluorophore.

Parameters E₁, f₁, and E₂, are the FRET efficiency of FRET state 1, fractional population of FRET state 1, and FRET efficiency of FRET state 2, respectively. See eqs 8-10 in ref. 21.
