Fig. 7. (a) The kinetic scheme for TPT in 2-MeTHF upon excitation centered at 600 nm. (b) Resulting rate coefficients from a fit of the kinetic scheme to TA data. kfiss was determined from fsTA data, and k5TT was given an upper bound based on estimated decay on a µs timescale. Φemi was fixed based on fluorescence quantum yield. kSQ and k1TT were varied in the fit of nsTA to match the 1TT and 5TT populations. Further details of the fit are in the ESI.†.
