Self- and H2-broadened width and shift coefficients in the 2 <f>←</f> 0 band of 12C16O: revisited

Room temperature values for self-broadened and hydrogen-broadened Lorentz halfwidth coefficients, and self and hydrogen pressure-induced shift coefficients have been measured for transitions with rotational quantum number <f>m</f> ranging between -24 and 24 in the 2 <f>←</f> 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. We have compared our results with similar measurements published recently. [Copyright &y& Elsevier]
