Abstract—

The H₂O foreign-continuum absorption in the IR region is considered within the asymptotic line wing theory, where absorption is represented as the sum of the absorption coefficients of individual lines of a special profile at far distances from the line centers. The line profile parameters pertaining to quantum and classical Н₂О–N₂ interaction potentials are found from fitting the experimental data on absorption in the 4200–5000 cm⁻¹ spectral range and on the temperature dependence of the second virial coefficient. This line profile is used for calculation of the continuum absorption in the 1000–10 000 cm⁻¹ range.

红外 H2O 波段翼中的外来连续吸收

摘要——

在渐近线翼理论中考虑了 IR 区域中的 H ₂ O 外来连续谱吸收，其中吸收表示为离线中心很远的特殊轮廓的各个线的吸收系数的总和。与量子和经典 Н ₂ О–N ₂相互作用势相关的线轮廓参数是通过拟合 4200-5000 cm ^-1光谱范围内的吸收实验数据和第二维里系数的温度相关性得出的。该线轮廓用于计算 1000–10 000 cm ^-1范围内的连续吸收。
