Kinetic analysis of the recovery of the C–O stretching vibration. a The early kinetics (5 μs to 1 ms) exhibit second-order recovery kinetics as shown by the linear behaviour of the plot 1/[Mb] vs time. b The later part of the recovery kinetics display first-order kinetics as shown by the linear behaviour of the plot ln{[Mb]/mM} vs time
