Measurements of the line strengths, N₂-, and O₂-broadened half-widths in the 2n₂+n₃ band of ¹⁴N₂¹⁶O at room temperature

Masashi FUKABORI, Tadao AOKI, and Takeshi WATANABE

　　The line strengths, N₂-, and O₂-broadened half-widths in the ₂n₂+n₃ band of ¹⁴N₂¹⁶O were determined from spectra obtained by a high-resolution Fourier transform spectrometer at room temperature. The squared vibrational transition dipole moment and the coefficients of the Herman-Wallis factor were also determined for this band. The measured line strengths agreed well with the values of HITRAN₂K. The N₂- and O₂-broadened half-widths were in agreement with the results of recent high-resolution experiments within the experimental errors. The air-broadened half-widths were calculated using the smoothed N₂- and O₂-broadened half-widths and compared with the values of HITRAN2K.
