How an nmr works
WebBoth IR and NMR spectroscopy are forms of absorption spectroscopy, but they don’t do the same thing. … Infrared radiation causes a vibrational transition in a given molecule. Chemists typically use infrared spectroscopy to identify functional groups that are present in the molecules. How does NMR work video? Why is NMR insensitive? WebNuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. ... Coupling to any spin-1/2 nuclei such as phosphorus-31 or fluorine-19 works in this fashion ...

WebSummary: NMR spectroscopy relies on detecting the precession rates of nuclear magnetic moments, which is sensitive to chemical environment. In HSQC, we let the magnetization sit with each nucleus for some amount of time, thus sampling the chemical environment of both nuclei. The result is a signal that we can plot on both proton and nitrogen ... http://www-keeler.ch.cam.ac.uk/lectures/Irvine/chapter5.pdf
