摘要

摘要利用布鲁克 FS-125M 傅立叶光谱仪研究了 7 种 NNO 同素异形体（14N14N16O、15N14N16O、14N15N16O、14N14N18O、15N15N16O、15N15N18O 和 15N14N18O）在 4200-6500 cm-1 范围内的吸收光谱，样品由 NO（80% 15N18O、20% 14N16O）和少量 N2O 同素异形体组成。测量谱线中心的误差为 0.0003 cm-1，测量谱线强度的误差为 5-15%。通过对测量数据集进行线轮廓参数拟合，确定了 27 个波段的光谱常数。测量线中心与计算线中心的标准偏差（0.0005-0.0027 cm-1）接近实验误差。

Studying the Absorption Spectra of NNO Isotopologues in the Region of 4200–6500 cm−1

The absorption spectra of seven isotopologues of NNO (¹⁴N¹⁴N¹⁶O, ¹⁵N¹⁴N¹⁶O, ¹⁴N¹⁵N¹⁶O, ¹⁴N¹⁴N¹⁸O, ¹⁵N¹⁵N¹⁶O, ¹⁵N¹⁵N¹⁸O, and ¹⁵N¹⁴N¹⁸O) are studied in the range of 4200–6500 cm⁻¹ with a Bruker FS-125M Fourier spectrometer, using a sample consisting of NO (80% ¹⁵N¹⁸O and 20% ¹⁴N¹⁶O) and a small number of N₂O isotopologues. The error in measuring line centers is 0.0003 cm⁻¹, and the error in measuring the intensities of lines is 5–15%. The spectroscopic constants of the 27 bands are determined by fitting the line contour parameters to the measured data set. It is noted that the standard deviation of the measured line centers from ones calculated (0.0005–0.0027 cm⁻¹) is close to the experimental error.
