摘要

摘要在 IFS 125HR 傅立叶光谱仪上记录了受气压影响而变宽的 3000-7500 cm-1 光谱区的 H2O 吸收线。H2O 吸收线强度是用改进的 Voigt 曲线确定的，该曲线考虑了宽化与碰撞分子速度的关系。结果与文献数据进行了比较。这项研究获得的 H2O 吸收线强度既可作为改进吸收线计算的基础，也可用于需要高精度强度值的不同大气应用中。

Water Molecule Absorption Line Intensities in the IR Spectral Region

H₂O absorption lines broadened by air pressure were recorded at an IFS 125HR Fourier spectrometer in the 3000–7500 cm⁻¹ spectral region. The H₂O absorption line intensities are determined with a modified Voigt profile, which considers the dependence of the broadening on the speed of colliding molecules. The results are compared with literature data. The intensities of the H₂O absorption lines obtained in this work can be used both as a basis for improving the calculations of absorption lines and in different atmospheric applications that require high precision intensity values.

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.
