Abstract : A Perkin-Elmer Model 12B infrared spectrometer was used with a LiF prism and an InSb photovoltaic detector to study the feasibility of using the emission spectra of noble gases produced in a hollow cathode discharge as wavelength standards in the 3 to 5.5 micron region. Argon is the best over-all standard in terms of the emission of sharp, nicely spaced lines with good intensities in this region from 4000 to 2000 reciprocal centimeters. However, xenon covers the region from 3200 to 2500 reciprocal centimeters best, and krypton is most useful between 2300 and 1850 reciprocal centimeters. Neon and helium are unsuitable as standards in the infrared.
