✦ Synopsis

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 parameters may be determined and the accuracy with which a spectral profile fits experimental data. Differences between a model profile and the experimental profile are quantified, and the underlying physics omitted from the spectral model is briefly discussed. Copyright 1998 Academic Press.

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

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. Th

The R(0) line profile of the 13 CO fundamental band is studied at low concentration in helium from room temperature (296.7 K) to 40 K. A narrowing effect due to molecular confinement (Dicke effect) is observed and analyzed using the Galatry soft collision model. The narrowing parameter is found to b

The pressure-induced shifting coefficients for He-, Ne-, Ar-, Xe-, N 2 -, and O 2 -broadened lines of CO in the fundamental band have been measured by using a Fourier transform spectrometer. The lineshifts have been determined from the wavenumber differences between the lines of pure CO at low press
