摘要：

A spectrometer for transient infrared absorption is described for samples which are exchanged or regenerated slowly. It is based on an excimer/dye laser system operating at 5-10 Hz repetition rate. Excitation pulses at 308 nm with 3 mJ energy are followed by infrared probe pulses which can be scanned continuously in the range 1950-4300 cm(-1). Infrared absorbance changes are detected with an accuracy of 1 mOD and a time resolution of 1.8 ps.
