Abstract: 
Infrared spectra of gaseous deuterium chloride have been measured with an interferometric spectrometer in the region of the fundamental vibration-rotational band with resolution 0.23 m-1. For these measurements the conditions were either a static sample of DCl in a conventional cell of length 0.27 m at 297 K or DCl in admixture with CO and argon flowing through a slit nozzle into an evacuated chamber. By means of adiabatic expansion the latter conditions produced a supersonic jet, in which the effective rotational temperature of both DCl and CO at the region of the measurements was (12 +/- 1.5) K. The relative precision 0.004 m-1 and absolute accuracy 0.04 m-1 of the measurements of the bands of (HCl)-H-2-Cl-35 and (HCl)-H-2-Cl-37 of the static gas make the lines suitable as secondary standards for calibration of the scale of spectrometers in the range of wavenumber 189,000 < nuBAR/m-1 < 224,000.
