An improved analysis of the N2O absorption spectrum in the 1.18 µm window

Résumé

A high-sensitivity absorption spectrum of natural nitrous oxide has been recorded at 10 Torr between 8321 and 8620 cm-1 (1.20-1.16 µm). The used cavity ring down spectrometer was referenced to a self-referenced frequency comb providing an accurate frequency scale of the spectra. The predictions of effective operator models were used for the line assignment. All identified bands correspond to the ΔP=14-16 series of transitions, where P= 2V 1 +V 2 +4V 3 is the polyad number (V i=1-3 are the vibrational quantum numbers). A total number of 3975 transitions belonging to the 14 N 2 16 O, 14 N 15 N 16 O, 15 N 14 N 16 O, 14 N 2 18 O, and 15 N 2 16 O isotopologues were measured with estimated accuracy
