Fig. 4: Vibrational relaxation dynamics of fundamental ground state transitions of pyruvate.

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

Fig. 4

a Relaxation dynamics of the fundamental asymmetric COO− and (b) the CO Stretch represented by the negative components of their diagonal signals (dots) from Fig.3. The absorption dynamics of the asymmetric COO− stretch is well approximated by the single exponential function: ΔA = −1.950 × exp(−t/0.6 ps) −0.016 (red line). The absorption dynamics of the CO stretch is well approximated by the single exponential function: ΔA = −1.60 × exp(−t/1.2 ps) −0.036 (red line). Source data are provided as a Source Data file.
