摘要

采用中红外波段连续可调谐二极管激光器和自行研制的低温吸收池, 测量了温度为296 K, 252 K, 213 K, 173 K时, 3.38 μm附近13CH4分子的四条跃迁谱线的氮气和空气加宽光谱; 首次通过实验获得空气和氮气对13CH4分子的碰撞加宽系数, 以及谱线加宽系数的温度依赖系数. 实验过程中, 利用Voigt线型对所测量的光谱进行拟合. 实验结果表明, 氮气和空气对13CH4分子的碰撞诱导加宽系数随温度的降低而增大; 相同温度下, 氮气对13CH4分子的碰撞加宽系数普遍大于空气加宽系数. 实验数据为地球和外星体大气遥感探测提供了依据.

Abstract

By using a mid-infrared tunable diode laser and a home-made cooling cell, the N2- and air-broadening coefficients of 13CH4 have been measured at room and low temperatures around 3.38 μm. Four transitions are studied for the 13CH4 diluted with nitrogen and air at temperatures 296, 252, 213, and 173 K. Measurements at low temperatures allow the determination of the temperature dependent parameter of the collisional broadening coefficients. The line parameters are obtained by fitting the experimental profile to the Voigt line shape. The N2- and air-broadening coefficients increase with the drop of the temperature. The collisional broadening coefficients of N2 are always larger than those of air at the same temperature. These data support the remote sensing of the Earth and outer planet atmospheres. According to our knowledge, the line parameters are reported experimentally for the first time.
