Abstract The pressure broadenings and shifts of rovibrational transitions of the CO fundamental band with foreign gases, Argon and Nitrogen, were measured by a tunable diode laser spectrometer. High J (≤34) R -branch and low J R - and P -branch transitions have been recorded with very high accuracy (5 × 10 −5 cm −1 ). These highly accurate and very sensitive measurements became possible with a newly designed shock-isolated laser cold head and the application of an extremely stable 50-m multiple-path cell of the Herriott type. The accuracy of the line shift and broadening coefficients obtained in the present study is about 3 × 10 −4 cm −1 /bar.
