Room temperature values for self-broadened and hydrogen-broadened Lorentz half width coefficients, and self and hydrogen pressure-induced shift coefficients have been measured for transitions with rotational quantum number index m ranging from -24 to +24 in the 2 0 band of ¹²C¹⁶O. The spectra were recorded with the McMath-Pierce Fourier transform spectrometer located at the National Solar Observatory on Kitt Peak. The analysis was performed using a multispectrum nonlinear least squares technique modified to constrain the Lorentz widths in the P and R branches to be identical for the same | m | value. We have compared the present results with our previous measurements made with the same spectrometer and with other measurements published recently.
