Abstract

A step-scan time-resolved Fourier transform infrared (FTIR) spectrometer was constructed. Using 1064 nm radiation from a 9ns pulsed Nd:YAG laser as the IR source, we have obtained both the time-resolved spectra in the frequency domain and the change of the transient signals in the time domain. The latter allows us to measure the time resolution of the instrument to be about 40 nanoseconds.
