Figure 6

(a) Spectra of the H13CN cell of 10-Torr pressure (1.0-GHz absorption linewidth) measured using 0.5-GHz resolution fr-sweeping FTS and a tunable continuous-wave (CW) laser (3-MHz linewidth). Raw experimental data (blue dots) of the fr-sweeping FTS used for Voigt fitting are plotted in the background. (b) Voigt-fitted absorption lines of P12 & P13 of the 10-Torr H13CN cell. For comparison, the absorption lines (dark yellow) from Fig. 5c measured with 1.1-GHz resolution from the 100-Torr H13CN cell are reproduced.
