Totally automated picosecond transient absorption spectrometer using two photodiode arrays as detectors

A totally automated picosecond transient absorption spectrometer is described. This experimental apparatus requires two photodiodes arrays as detectors and a single spectrograph. It takes advantage of the high dynamic range of such detectors. Typical transient spectra are presented. They show the reproducibility and accuracy of this method of time‐resolved spectroscopy.
