quantum mechanics - Is there a way to "hold a molecule still"?


Is there a way (even if only theoretical) to hold all the nuclei of one single molecule in place, stoping them from vibrating and stoping the molecule completely (0 kinetic energy)? If so, what happens to the electrons when the molecule is trapped like that?


EDIT: Let me add some more information, in the form of assumptions that I had prior to ask this question:



  1. I assumed all molecules move through space, even in a solid or liquid, even though they move less than a gas molecule.

  2. I assumed, that there is movement inside the molecules, their nuclei would change their position in relation to an arbitrary point $P_0$ that would be the "origing point of the molecule".

  3. I assumed it was possible (and very common) to be able to restrict the first kind of movement during physics experiments, but I wasn't sure about the second kind, since, in my naïve assumption, that movement was the result of interactions between the atoms of the molecule.
