11-1 Nuclear Magnetic Resonance Spectroscopy Many atomic nuclei behave as if they spin on an axis of rotation -Nuclei are positively charged These spinning nuclei generate tiny magnetic fields Tiny magnets interact with an external magnetic field,denoted Bo Proton (1H)and carbon (13C)are the most important nuclear spins to organic chemistsMany atomic nuclei behave as if they spin on an axis of rotation ▪ Nuclei are positively charged ▪ These spinning nuclei generate tiny magnetic fields ▪ Tiny magnets interact with an external magnetic field, denoted B0 ▪ Proton (1H) and carbon (13C) are the most important nuclear spins to organic chemists 11-1 Nuclear Magnetic Resonance Spectroscopy
