Rapid-scan Millisecond Time-resolved FT-IR Measurements... 

The static technique able to re.solve reactions on the second-time scale is easie.st to perform and a good point to start with. The reaction can be slowed down by variation of external parameters. The rapid. scan technique can resolve already millisecond reactions and has the broadest applicability. A time resolution of microseconds is most easily... 

The combination of the high sensitivity of SEIRAS and a rapid-scan FT-IR spectrometer enables the spectral collection simultaneously with electrochemical measurements such as cyclic voltammetry and potential-step chronoamperome-try. The time-resolved measurement can give some information on electrode kinetics and dynamics, as has been shown in Fig. 8.24. Figures 8.25 and 8.26 represent another example of millisecond time-resolved ATR-SEIRAS study of current oscillations during potentiostatic formic acid oxidation on a Pt electrode [123]. At a constant applied potential F of 1.1 V, the current oscillates as shown in Fig. 8.25 a. Synchronizing with the current oscillations, the band intensities of linear CO and formate oscillate as shown in Fig. 8.26 (and also in Fig. 8.25 c).
