I recently learned about the "watering hole," a group of frequencies between 1.42 and 1.66 GHz. I also read that microwave ovens operate at 2.4 GHz.
If 21 to 18 cm (1.42 to 1.66 GHz) is the resonant frequency of hydrogen and hydroxyl, respectively, how do I arrive at the resonant frequency of water using those numbers? Is the resonant frequency 2.4 GHz (approx) based on the frequency microwave ovens use?
I guess what I am clearly trying to ask is: Is resonance of a molecule (like water) determined by constituent parts (as I am supposing) or are there other considerations?
And as I look at this question, why does hydrogen, something that is less massive, have a lower frequency resonance? Is it because there is less mass requiring less force to move it to resonance, are my facts incorrect, or is there something I'm going to learn with the answer to the first part of the question?
