论文摘要
介绍了HiteMP光谱数据库的甲烷线列表，涵盖0-13,400 cm $^{ - 1} $（$> $ 746 nm）。要创建此汇编，请从Rey等人的$^{12} $ ch $ _ {4} $的$^{12} $ ch $ ch $ _ {4} $列表。 （2017）APJ，847，105（在理论信息系统中的单独温度下提供），现在与HITRAN2016甲烷数据结合使用，以产生适用于高速逐线计算的单线列表。最高2000 k的高温逐线计算。为有效的温度插入模型，以表现出持续性的持续性特征。该模型对于采用所谓的``超级线''的先前使用的方法有利，该方法仅在给定温度下适合，并且需要单独的线列表以进行不同的温度。最终的Hitemp行列表包含$ \ sim $ 3200万行，并且比甲烷的替代行列表明显更灵活，同时保留了天体物理或燃烧应用所需的准确性。与高温下甲烷吸收的实验观察的比较已被用来证明新作品的准确性。该行列表既包含强线和准圆顶的特征，又在常见的用户友好的Hitran/hitemp格式中提供，使其成为在高温条件下用于辐射传输建模的最实用的甲烷线列表。
A methane line list for the HITEMP spectroscopic database, covering 0-13,400 cm$^{-1}$ ($>$746 nm), is presented. To create this compilation, ab initio line lists of $^{12}$CH$_{4}$ from Rey et al. (2017) ApJ, 847, 105 (provided at separate temperatures in the TheoReTS information system), are now combined with HITRAN2016 methane data to produce a single line list suitable for high-temperature line-by-line calculations up to 2000 K. An effective-temperature interpolation model was created in order to represent continuum-like features at any temperature of interest. This model is advantageous to previously-used approaches that employ so-called ``super-lines'', which are suitable only at a given temperature and require separate line lists for different temperatures. The resultant HITEMP line list contains $\sim$32 million lines and is significantly more flexible than alternative line lists of methane, while accuracy required for astrophysical or combustion applications is retained. Comparisons against experimental observations of methane absorption at high temperatures have been used to demonstrate the accuracy of the new work. The line list includes both strong lines and quasi-continuum features and is provided in the common user-friendly HITRAN/HITEMP format, making it the most practical methane line list for radiative transfer modeling at high-temperature conditions.
