Schematic of the nanosecond ss-FT-IR and the connectivity of the FT-IR. Data collection starts with an initiation signal from the FT-IR going to the function generator and providing a reset signal to the boxcar integration modules. The output from the function generator, described in the text, is passed through a delay generator, which sends pulses to the boxcars and laser. The homemade purged box contains the sample chamber, where the sample is excited from two sides. In the last step the boxcars send the data back to the FT-IR for acquisition and processing.
