Time-resolved conventional IR techniques

Further improvement is achieved using a picosecond-pulsed laser light source in contrast to a continuous one. Time resolution thus is determined by the lifetime of the probe beam instead of the response time of the detector in analogy to picosecond time resolved experiments in the visible spectral range (for a recent review see Stoutland et al., 1992). 

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
