Interpreting carbon nmr
WebVideo transcript. - The nucleus of a Hydrogen atom is a proton and has a property called spin. So you can think about, just as a visual aid, you can think about this proton that's spinning this way. A spinning proton, right, is like a rotating sphere of charge, and any moving charge creates a magnetic field. Webcompletely, your calibration will be wrong. Also, carbon-13 and other nuclei can relax extremely slowly (tens of seconds). Use of relaxing agents in these cases may be very …
