Lifetimes

Please provide the line list files.

If you want to save compressed .states.bz2 file, please wirte Y after Compress(Y/N), otherwise, if you write N, the uncompressed .states file will be saved.

The lifetimes equation is:

\[ \tau_i = \frac{1}{{\textstyle \sum_{f} A_{fi}}}. \]

Note

If the line lists data is not in the ExoMol format, please convert your data format into the ExoMol format at first and then compute lifetime with PyExoCross. So please read Conversion and write 1 after Conversion, 2 after ConversionFormat and fill Conversion section.
