What Forces Cause Rotational Emissions?

  1. Nov 7, 2015 #1
    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?
