Figure 5.

Picosecond TRIR spectra of Re^I(dmp)(W)AzZn^II measured at selected time delays (in ps) after 400 nm, ~150 fs excitation. Experimental points are separated by 4-5 cm⁻¹. The arrows show the relaxation-related ³CT band shifts (the small ³CS rise is apparent only after background subtraction). Solution in 50 mM KPi buffer in D₂O (pD ~7.0) at 21 °C.
