Before someone accuses me of being a half-wit attemtping to explore fields way beyond my intelligence, I'll just come straight out right now and say: "My highest level of education is that of a highschool graduate"! I am however, on a very serious trip to learn as much as I can about the attractive interactions between molecules and subatomic particles. So if you can help, please do so by answering my questions below. If my questions don't make sense, don't call me a half-wit, simply invite me to re-ask the question or elaborate: 1-Is Nuclear Magnetic Resonance and Proton Magnetic Resonance essentially the same thing? (i.e. in both instances, the participating particle is the proton). If no, what are the defining differences? Can you clearly define NMR? and PMR if different? 2-Does Electron Magnetic Resonance trigger a similar event as Nuclear Magnetic Resonance? If no, what is the defining difference? Can you clearly define EMR? 3-Systemically describe the events leading up to achieving magnetic resonance? 4-Is the following statement accurate: "every chemical element has a unique NMR frequency that distinguishes them apart!"? If this is true, does this also mean that a precisely transmitted RF pulse will dictate whether work performed is work associated with NMR, PMR, or EMR? Thank you in advance for your thoughts, and comments. Please note: If an example-molecule is necessary to help answer my questions, let's use "water".
