摘要：

Fourier transform absorption spectra using the sun as a source have been recorded, from a balloon at an altitude of 37.92 km, in the spectral region 1400-2000 cm-1 for a solar zenith angle of 80.65-degrees. From the detailed analysis of 11 lines of H216O, 19 lines of H218O and 3 lines of H217O the following isotopic enhancement factors have been obtained with respect to H216O: rho-(H218O) = 0.97 +/- 0.06 rho-(H217O) = 1.16 +/- 0.15 A careful analysis of the errors involved has been performed. For H218O and H217O. these result confirm previous observations by mid- and far-infrared spectrometry, which show no evidence of significant stratospheric enhancements.
