利用二极管激光腔衰荡光谱分别测量了氧化亚氮同位素物14N15N16O和15n14n16o在6400-6463和6465-6532 cm-1的3ν3波段的吸收光谱。测定了光谱参数和谱带的旋转谱线强度。我们已将这种光谱技术应用于利用绝对谱线强度测量这些同位素物的绝对同位素比率。
The absorption spectra of the 3ν3band of nitrous oxide isotopologues,14N15N16O and15N14N16O, have been measured using diode laser cavity ring-down spectroscopy in 6400–6463 and 6465–6532 cm-1, respectively. Spectroscopic parameters and the rotational line intensities of the bands have been determined. We have applied this spectroscopic technique to the measurements of the absolute isotope ratio of those isotopologues using the absolute line intensities.
