Both IR and NMR spectroscopy are forms of absorption spectroscopy, but they don't do the same thing. IR spectroscopy stands for infrared spectroscopy. It involves studying the absorption of infrared radiation. Infrared radiation causes a vibrational transition in a given molecule. 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. form 14135 irs
