Abstract:

Continued improvements in instrumentation have led to a wide use of infrared transmission spectroscopy, and have permitted the examination of samples of limited transparency. However, although there is no particular problem with samples having about 2 transmittance or more, considerable difficulties arise if the transmittance is in the fractional percent range. The present paper is concerned with such energy-limited spectral measurements. The effects of self-emitted radiation, ordinate expansion, and scan time are considered. Author
