In spite of the nucleus being crucial to NMR in that the technique is only useful with certain configurations of the nucleus, [https://www.youtube.com/watch?v=TJhVotrZt9I the electrons of an atom do influence how much an atom is diamagnetically shielded from the effects of RF.] | In spite of the nucleus being crucial to NMR in that the technique is only useful with certain configurations of the nucleus, [https://www.youtube.com/watch?v=TJhVotrZt9I the electrons of an atom do influence how much an atom is diamagnetically shielded from the effects of RF.] | ||
* Ultimately, you are producing a spectrum with NMR. | |||
* The height on the Y-Axis predictably represents how much of something there is. | |||
* The X-Axis represents resonance at different frequencies. | |||
** If you are performing the typical Hydrogen-1 (Proton NMR) analysis of a sample, where these peaks are on the X-Axis represents different ways the electrons of a given Hydrogen within a compound are configured. For a simple compound where there is hydrogen in just one configuration (H2O / Water), you'd expect one peak. For Ethanol, CH3-CH2-OH, we'd expect three peaks. | |||
