“…In the past, most of the previous rotational transition measurements were performed on the dominant isotopologue, i.e., N NO [29]. For N NO and N NO, however, very few reports can be found [29], [30]. By frequency tuning our THz source, we have identified 29 new transition peaks for these two isotopic variants.…”

Different gases have been successfully fingerprinted on the basis of the distinct transition frequencies measured by frequency tuning a THz source developed by us. Our further analysis illustrates that one can reliably separate isotopologues by measuring and comparing their rotational constants. Based on our investigation of the N 2 O isotopologues, 29 rotational transition peaks were identified for the first time. For the gas mixtures, preliminary results indicate that one can identify the components of chemical species and the corresponding concentrations. Based on our spectroscopic results, the tunable THz source may offer a viable approach in the identifications and detections of chemical species. Index Terms-Identifications and detections of chemical species, rotational transitions, terahertz (THz), transmission and absorption spectroscopy.

“…Similar to CO, N O naturally consists of several isotopologues. In the past, most of the previous rotational transition measurements were performed on the dominant isotopologue, i.e., N NO [29]. For N NO and N NO, however, very few reports can be found [29], [30].…”

“…As a consequence, the high-resolution spectra of this molecule are widely used for the monitoring of its concentration in atmosphere and in the combustion exhaust. 15 [1][2][3], Fourier-transform infrared spectrometers (FTS) [4][5][6][7][8][9][10], intra-cavity laser absorption spectrometer (ICLAS) [11], and cavity ringdown spectrometer (CRDS) [12,13]. All the above listed measurements were carried out with natural nitrous oxide samples.…”

“…However, the high-resolution study of most minor isotopologues of many polyatomic molecules is not yet complete. Therefore, we have undertaken a systematic absorption spectroscopy study of the isotopologues of the main atmospheric species from the midinfrared to the near-infrared: D 16 16 O molecule have been performed using microwave (MW) [12], Fourier-transform infrared (FTIR) [13,14], intra-cavity laser absorption spectroscopy (ICLAS) [15], and cavity ring-down spectroscopy (CRDS) [16,17]. Since most of these measurements were carried out with natural nitrous oxide samples, high resolution spectra of 15 N 14 N 16 O are still rather scarce, especially in the near-IR region.…”
