NMR Spectroscopy Chemical Shifts Δ Frequency Shift From Me 4 Si In Hz Spectrometer Frequency M Hz E B E B O B B O B E Ν O ΓB 2 Π H A Magnetic Field At Nucleus Larmor Precession Frequency Of H A Chemical Shifts Have Their Origin In The Circulation Of Electrons Induced By The Magnetic Field Which Reduces The Actual Field At The Nucleus Thus A Higher Magnetic Field Has To Be Applied To Achieve Resonance Different Types Of Protons In A Molecule Are Surrounded By Different Electron Densities And Thus Each One Sees A Slightly Different Magnetic Field Reich Chem 345 Univ Wisconsin Madison The Larmour Precession Frequency Ν O Depends On The Magnetic Field Strength Thus At A Magnet Strength Of 1 41 Tesla Protons Resonate At A Frequency Of 60 M Hz At 2 35 Tesla At 100 M Hz And So On Although Hz Are The Fundamental Energy Unit Of NMR Spectroscopy The Use Of Hz Has The Disadvantage That The Position Of A Peak Is Dependent On The Magnetic Field Streng
