Abstract:Frequency measurements are given for the 10$^0$0-00$^0$0 band of N$_2$O near 4.5 $\mu$m and for pure rotational transitions beyond 151.5 $\mu$m. The infrared measurements utilize a periodically-poled lithium niobate (PPLN) based difference frequency generation (DFG) source locked to the saturated absorption center of an N$_2$O absorption line. The DFG frequency is calibrated by an optical frequency comb and an iodine hyperfine transition. We report 44 transitions ranging from $J$ = 1 - 100 for both the $P-$ and $R-$ branches and the accuracy is better than 10 kHz for most transitions. In addition, 175 pure rotational transitions have been measured including 33 measurement with sub-Doppler precision ($<$ 3 kHz), and 142 Doppler limited measurements. These are combined with other precision rotational and vibrational measurements to provide improved quantum mechanical parameters as well as frequency calibration tables for the N$_2$O bands near 4.5 $\mu$m.
