A laboratory emission spectrum of TiO in the visible and near-infrared regions (476–1176 nm) has been calibrated and corrected. High-resolution experimental absorption cross sections for TiO with natural isotopic abundance are provided at a temperature of about 2300 K. These cross sections have been compared with those derived from the ExoMol line list. The experimental cross sections can be used directly as a template for cross correlation TiO detection in hot Jupiter exoplanets.

测量的 TiO2 光吸收截面

TiO 在可见光和近红外区域（476-1176 nm）的实验室发射光谱已经过校准和校正。在大约 2300 K 的温度下提供了具有天然同位素丰度的 TiO 的高分辨率实验吸收截面。 这些截面已与来自 ExoMol 线列表的截面进行了比较。实验截面可直接用作热木星系外行星中二氧化钛互相关检测的模板。统一天文学辞典概念：分子光谱学 (2095)；高分辨率光谱（2096）；线强度（2084）；M 星 (985); 系外行星大气成分 (2021) 支持材料：数据背后的数据
