I describe how the collisional‐radiative model used in the analysis of fusion plasmas is an extension of the simpler coronal model familiar from astrophysics, and discuss what happens when hydrogen molecules are a component of the plasma. I give a brief description of a criterion for the validity of a collisional‐radiative model, and show that the criterion is particularly important when molecules are present. I apply the collisional radiative model to Fulcher band spectroscopy and show that the analysis of vibrational spectroscopy of molecules with a collisional‐radiative model contains unexpected, but useful features.
