A lines shape of the first triplet of rotational band of oxygen molecule was studied beyond the Voigt profile in the framework of the quadratic approximation of speed dependence of collision relaxation rate. Recordings of the lines broadened by O2 and N2 were obtained at room temperature using two fundamentally different spectrometers, in particular, a video spectrometer and a spectrometer with radio-acoustic detection of absorption. A set of line-shape parameters was determined based on the line recording analysis. Data accuracy and reliability was evaluated from a comparative analysis of the parameters obtained from different techniques and with previous data.

氧第一旋转三重态的线形参数


在碰撞弛豫率的速度依赖性二次近似框架内，研究了氧分子旋转带的第一个三元组的第一个三元组的线形。在室温下，使用两种基本不同的光谱仪，特别是视频光谱仪和具有放射声吸收检测功能的光谱仪，获得了由 O2 和 N2 加宽的谱线的记录。根据线记录分析确定了一组线形参数。通过对从不同技术和先前数据获得的参数进行比较分析来评估数据的准确性和可靠性。
