分析了(a)天然丰度水蒸气、(b) (H2O)- o -18富集水蒸气和(c) (H2O)- o -17富集水蒸气记录的傅里叶变换光谱。利用三个光谱的强度比，对927条被(H2O)-O-18吸收的谱线进行了鉴定。导出了这些线的强度和自展宽参数。利用理论谱线，与先前分配的(H2O)-O-16光谱进行比较，并自动搜索组合差异，分配了747条谱线。这些线属于3nu + delta和4nu polyad中的14种振动状态。新确定的(H2O)-O-18振动带起源包括：13793.09 cm（-1）处的4nu(1), 13795.40 cm（-1）处的3nu(1) + 2nu(3), 14188.82 cm（-1）处的2nu(1) + 3nu(3), 14276.34 cm（-1）处的nu(1) + 3nu(3), 13612.71 cm（-1）处的2nu(2) + 2nu(2) + nu(3)。这些结果与HITRAN数据进行了比较。(C) 2002 Elsevier Science （USA）。
Fourier transform spectra recorded using (a) natural abundance water vapor, (b) (H2O)-O-18-enriched water vapor, and (c) (H2O)-O-17-enriched water vapor are analyzed. The ratio of intensities in three spectra is used to identify 927 lines due to absorption by (H2O)-O-18. Intensities and self-broadening parameters are derived for these lines. Using theoretical linelists, comparisons with previously assigned (H2O)-O-16 spectra, and automatic searches for combination differences, 747 lines are assigned. These lines belong to 14 vibrational states in the 3nu + delta and 4nu polyads. Newly determined (H2O)-O-18 vibrational band origins include 4nu(1) at 13 793.09 cm(-1), 3nu(1) + nu(3) at 13 795.40 cm(-1), 2nu(1) + 2nu(3) at 14 188.82 cm(-1), nu(1) + 3nu(3) at 14 276.34 cm(-1), and 2nu(2) + 2nu(2) + nu(3) at 13 612.71 cm(-1). These results are compared with data in HITRAN. (C) 2002 Elsevier Science (USA).
