✦ Synopsis

Using a difference frequency spectrometer we have measured the widths, shifts and line mixing parameters of many lines in the fundamental band of CO perturbed by N 2 at approximately 50 kPa and 301 K. The spectral resolution was 6 1 10 05 cm 01 and the typical signal to noise ratio exceeded 2000. The spectral data are more extensive and more precise than the data currently used in the HITRAN92 database. At the 1% level we have reached the limit of accuracy with which a Lorentzian model will represent the data.

We have measured the width, Gamma, of many P and R lines of the fundamental vibration-rotation band of CO perturbed by N(2) at 348 K and pressures of about 50 kPa. We have also extended the measurements made earlier at room temperature. The broadening coefficients, gamma = Gamma/pressure, were obtai

The collisional relaxation of the J = 5 ← 4 rotational transition of CO induced by carbon monoxide, nitrogen, and oxygen has been studied at room temperature. Pressure-broadening parameters were determined as 3.29(2), 2.61(2), and 2.30(2) MHz/Torr for CO, N 2 , and O 2 buffer gases, respectively. Ex

We present accurate broadening coefficients for many lines of the fundamental band of CO highly diluted in He and Ar at 301.5 K. It is shown that a soft collision model gives a reasonable fit to the data at pressures up to 1 atm. A distinction is drawn between the accuracy with which fitting paramet
