Figure 2.

(a) Typical [CH₂OO]_t time profiles in the presence of different concentrations of CH₃CHO (blue) (labeled A and B) at 295 K; (b) as (a) but different concentrations of C₂H₅CHO (red) (labeled C and D). Error bars are 1σ uncertainties in the concentrations derived from fitting the transient absorption spectra. Solid lines are fits to the integrated rate equation, and shaded areas represent 1σ prediction bands. (c) Pseudo-first-order plot of k_loss against [RCHO] at 295 K. The specific data points corresponding to time profiles A–D in panels (a) and (b) are highlighted. Vertical and horizontal error bars represent the 1σ statistical uncertainty in fitting CH₂OO concentration profiles and uncertainty arising from aldehyde concentration calibration measurements, respectively. Solid lines are linear fits and shaded areas represent 1σ prediction bands.
