Abstract

The effect of a most general spectrometer response function (slit function) on the measured transmission and emission of gases is investigated. It is shown that, although both the measured absorption and emission of hot gases are distorted by the slit function, the temperature determined by the infrared monochromatic radiation method is independent of the slit function. It is also shown that the conditions for the invariance of the integrated transmission are much milder than those previously assumed.
