Abstract

The experimental determination of the resolving power of infrared spectrometers by means of sharp absorption lines is discussed. Under certain conditions the convolution of the true line profile with the monochromator function approximates completely to the latter, from where the spectral slit width can be obtained immediately. Some suitable lines in the absorption spectra of small gas molecules are suggested for calibration purposes.
