It just depends on the wavelength, not the power. Microwave frequencies aren't atomic scale, but your microwave oven uses a frequency that fits a H2O molecule 'good enough' at some fraction of the paticular microwave frequency to make it rotate despite the interactions of the other chicken pot pie molecules - the amount of heat generated attests to the fact that the other particles put up a good fight..
If you really wanted to obliterate some H2O, I think you have to go to gigahertz frequencies, but there is a point when any sufficiently high enough freq will toast pretty much anything.
I mean, I guess? Who/really/ knows anyway..lol.
