What Forces Cause Rotational Emissions?

AI Thread Summary
Rotational emissions occur when a molecule transitions to a lower spin state, releasing energy as low-energy photons in the micro and radio frequency range. This process is governed by quantum mechanics and is distinct from vibrational emissions, which emit infrared radiation. The discussion seeks methods to intentionally lower a molecule's spin state to induce rotational emissions, exploring potential protocols involving magnets or voltage changes. Understanding these mechanisms could enhance applications in astronomy and microscopy. Further insights or clarifications on these methods are welcomed.

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?
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
