Recent studies have demonstrated how effective the time-resolved Fourier transform spectroscopic technique is in obtaining dynamic information about microstructural change in the millisecond time scale. In this current study, the time efficiency of the method has been improved by the development of a scheme implementing the use of a separate microprocessor to maintain synchronization between the interferometer movement and the external event. This method eliminates the need for accurate external timing circuits and their interface to the FT-IR. Therefore, data collection software of the FT-IR system need not be modified as in previous cases.
