Absorption linewidths associated with microwave transitions across -doublets and pure rotational transitions of the free hydroxyl radical OH perturbed by N 2 , O 2 , and Ar are computed for temperatures ranging from 194 to 300 K within the framework of the Robert-Bonamy semiclassical formalism using
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 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
Infrared line positions, linestrengths, and pressure-broadening coefficients are required to determine absolute trace gas concentrations from high-resolution absorption spectra. We have measured these values for the infrared absorption lines in the ฮฝ 12 band (antisymmetric wag) of hydrazine between
