Analysis of tunable diode-laser spectra of RQ( J,0) lines in CH 3F near 1475 cm -1 using a multispectrum fitting technique
We have analyzed the methyl fluoride RQ(J,0) Q branch lines located near 1475 cm -1 using a simultaneous multi-spectrum fitting technique. In this analysis we have used previously recorded diode-laser data in which we collected many data points covering only one or two Q branch lines in a particular run. The analysis consists of simultaneously fitting 57 spectra collected with numerous pressure and path length conditions for all absorption lines. The data are concatenated to create one continuous spectrum of the Q branch. We have determined the intensity and self-broadened widths at 296 K for 23 RQ( J,0) lines.
