Electron spin resonance millions

The principal source of structural information in high-resolution NMR spectroscopy is the chemical shift, which originates from the shielding of the spin nucleus from the external magnetic field by the small magnetic field induced by the motions of the electrons surrounding the nucleus. Thus, the nucleus experiences an effective field, B = (1 - c)Bq, where n, the shielding constant, is a dimensionless number, usually listed in parts per million. This leads to a small modification of the resonance condition in Equation 6.1 ... [Pg.224]
