What Forces Cause Rotational Emissions?

Click For Summary
SUMMARY

Rotational emissions occur when a molecule transitions to a lower spin state, releasing energy as low-energy photons, typically in the micro and radio frequency range. This phenomenon is governed by quantum mechanics (QM) and is distinct from vibrational emissions, which emit infrared radiation. The discussion highlights the need for methods to lower a molecule's spin state on demand, exploring the potential use of magnets and voltage changes to achieve this effect.

I was curious about what forces can be applied to a molecule to cause a rotational emission.

What is a rotational emission?
 
Essentially, rotational emission is caused when there is a change in a molecules spin state to a lower energy, the difference is released in the form of a low energy photon (somewhere around micro and radio frequencies). Its similar to vibrational emissions, but those release infrared, both behaviors a governed by QM though. Its used in astronomy and a few forms of microscopy.
(I am a little shaky on the specifics myself. If someone has a better explanation or more to offer, its always appreciated!)

So to be more specific, I am wondering what methods can be implemented to lower a molecules spin state on demand, so that it results in an emission.
Are there protocols for using magnets, or changes in voltage, etc. , that can cause such an effect?
