Top: Nanosecond TRIR spectra of 4.4 mM ReI(dmp)(W)AzZnII measured at selected time delays (in ns) after 355 nm, ~0.7 ns excitation. Experimental points are separated by 4-5 cm-1. Bottom: DAS obtained by SVD/global fitting. The 1300 ns lifetime was fixed in the analysis, based on ReI(dmp)(Y)AzZnII emission decay. The spectra evolve in the direction of the arrows. Solution in 50 mM KPi buffer in D2O (pD ~7.0) at 21 °C.
