Paper Abstract

The availability of commercial step-scan FT-IR instrumentation has led to the rapid development of a number of new and rediscovered applications. These take advantage of the peculiar features of step-scan FT-IR, for instance, separation of spectral and temporal multiplexing. This paper describes experimental arrangements for several studies including modulation spectroscopy, time resolved spectroscopy (TRS), vibrational circular dichroism, and photoacoustic spectroscopy. The use of devices external to the spectrometer (e.g., lock-in amplifiers) is described, with attention to multiple channel data collection.
