摘要

摘要研究了水蒸气在 14 800-15 500 cm-1 光谱区的傅立叶吸收光谱，分辨率为 0.05 cm-1，光路长度为 3480 cm。详细列出了 H216O 的 906 条确定的吸收线和属于 19 种振动状态的 426 个能级。首次确定了 55 个能级，并对 64 个能级的能量进行了校正。与文献中的数据进行了比较。解析度较高、不太弱的线的位置误差为 0.002 cm-1，强度误差为 10-15%。

LED Fourier Spectroscopy of H216O in the 14 800–15 500 cm–1 Spectral Region

Fourier absorption spectrum of water vapor is studied in the spectral region 14 800–15 500 cm^–1 with a resolution of 0.05 cm^–1 and an optical path length of 3480 cm. A detailed list of 906 identified absorption lines of H₂¹⁶O and a set of 426 levels energies belonging to 19 vibrational states are compiled. Fifty-five energy levels are determined for the first time, and the energies of 64 levels are corrected. The comparison with the data available in the literature is made. The error in the positions of well-resolved, not very weak lines is 0.002 cm^–1, and the error in intensities is 10–15%.

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
