Changing the 3D Structure of Molecules: Methods and Feasibility

[mather]

Hello

I want to know the available methods to change the 3d structure of a molecule

Thanks

It is like saying "I want to know all prime numbers". There are infinitely many, so you can't.

But perhaps the question is in fact more precise or asked in some context, which limits possible answer space.

Well i was expecting something like:

By providing energy, thermal, electrical, magnetical.

By chemical reaction.
By mechanical force, using nanodevices.

Etc.

But a bit more precisely. Also, are all these methods feasible? Last, any other method?
