Cavity ring-down spectroscopy of the bands of 15N substituted N2O

摘要: Abstract The 6 ν 3 and 2 + − bands of 15N substituted nitrous oxide isotopologues have been recorded by a continuous-wave cavity ring-down spectrometer (CW-CRDS) operated near 0.8 μ m . sensitivity limit was at the level 1 × 10 / cm In total, 213, 86 191 transitions were observed for 14N15N16O, 15N14N16O 15N216O isotopologues, respectively. ro-vibrational spectroscopic parameters upper states are determined from least square fitting transitions. absolute line intensities cold retrieved multi-line procedure spectra with an estimated accuracy 4% majority unblended lines. vibrational transition dipole moment squared values empirical Herman–Wallis coefficients also presented.
