(a) If we fit the TRPES spectra analogously to adenine, we extract a <50 fs channel and a channel with a 1140 fs, 1020 fs, and 750 fs lifetime for cytosine, thymine, and uracil respectively, while keeping the long-lived channel fixed to 1ns. The error of the global fit is slightly worse than with the approach presented in the text; (b) If we fit the 250 nm adenine data analogously to the other bases, as described in the text, we fix the long-lived channel fixed to 1 ps as suggested in ref. 8, and extract a <50 fs channel and a 360 fs channel. At 267 nm excitation, however, this fitting procedure fails as it appears to be missing a long-lived (ns) channel.
