Line parameters of 15N216O from Fourier transform measurements in the 5800 - 7600 cm-1 region and global fitting of line positions from 1000 to 7600 cm-1

Abstract

Using FT spectra (unapodized resolution ~ 0.0056 cmˉ¹)) of nitrous oxide isotopologue 15N216O, the line positions and intensities have been measured for 511 lines of 8 cold and one hot bands lying between 5800 and 7600 cmˉ¹. A multispectrum fitting procedure has been used to retrieve line parameters from 5 experimental spectra recorded at different pressures. An absolute wavenumber calibration has been performed using acetylene line positions around 6500 cmˉ¹ and water line positions in the 7100-7300 cmˉ¹ region. The average absolute accuracy of the line parameters obtained in this work has been estimated to be ± 0.0005 cmˉ¹ for the line positions, 2-5% for the line intensities depending on the transitions. For each studied band, the vibrational transition dipole moment squared value and the empirical Herman-Wallis coefficients have been adjusted. Moreover the line positions measured in this work and those collected from the literature allowed the global fitting of the effective Hamiltonian parameters for this isotopologue.
