Abstract

The influence of experimental geometry on the signal strength and signal-to-noise ratio of infrared spectrometry has been investigated. In general, it was found that the choice of optimum experimental geometry depended on the orientation of the vibrational mode being investigated. In particular, it has been calculated that internal reflection spectrometry is relatively insensitive to vibrational modes perpendicular to the surface relative to transmission spectroscopy at Brewster's angle, and this has been confirmed by experiment.
