Fig. 7: Photoproducts from aqueous pyruvate following excitation at 200 nm.

From: Aqueous pyruvate partly dissociates under deep ultraviolet irradiation but is resilient to near ultraviolet excitation

Fig. 7

a Transient absorption dynamics showing the formation of CO2(aq). 2D contour plot of Fig. 7a is shown in Supplementary Fig. 2. b Transient absorption trace recorded at 2341 cm−1 (dots). The transient 2341 cm−1 is well approximated by the function: ΔA = −0.67 mOD× exp(−t/1.7 ps) −2.0 × exp(−t/13.9 ps) + 2.58 mOD (red line). c Steady state infrared absorption spectrum of acetic acid recorded in H2O against a H2O reference. Source data are provided as a Source Data file.
