========================
Get Molecular Parameters
========================

Retrieve isotopologue abundances or molecular mass, based on HITRAN data,
using :py:class:`~radis.db.molparam.MolParams`

See also how to use custom (non-terrestrial) abundances in
:ref:`the Custom Abundances example <example_custom_abundances>`
