Could a physical (or energy based) deployment method allow for the destruction of complex molecules into single molecules or smaller particles? Specifically, I am looking for a finite duration effect. The idea is simply to break down complex matter but not remove it from existence if possible. The effect must last for a 5-10 second time frame, I'm almost looking for molecular decay, but not radioactive decay.
Please assume tech level is not capped for this question, I'm looking more at the science part.
I considered the usage of anti-matter to break materials down, however most of my research shows anti-matter simply creating gamma rays in this manner.
I moved towards the localized negation of the Coulomb force, or at least the reversal but since I'm no rocket scientist, I didn't get far.
Finally I postulated reversing the electrons that hold together bonded atoms, hopefully forcing them to split.
I just don't know if any of this is possible, or if I'm looking at it from the wrong angle.
Edit: Considering hitting the target with energy to achieve the result, would a selective method, focusing on certain compounds be feasible? Perhaps by using certain charged electrons or something.
