Radiative de-excitation in a plasma

Hello,
I am using the plasma module and wanted to include radiative de-excitation reactions. For example, I want to include the transition from N2C to N2B with a wavelength of 337.1 nm. I know that COMSOL has Plank's constant. If I give it a wavelength I get a Token error, Position: 11, Reaction: 0. Has anyone done this before? Is there a way to include radiative de-excitation?
Thank you.

Arber,
Radiative decay reactions can be implemented just like any other reaction (e.g. N2C=>N2B), but don't include the photon in the reaction equation. To account for radiation trapping, you will need to either include some type of factor in the rate expression or solve for the radiation transport.

Thanks Luke. Comsol support just replied with the same answer. They said there is an example model
Model Library>Plasma Module>Inductively Coupled Plasmas>electrodeless_lamp
I guess I was overthinking it. Thanks again.
