the benzene molecule In some cases. such as the benzene molecule. the circulation of the electrons in the aromatic orbitals creates a magnetic field at the hydrogen nuclei which enhances the b. field This phenomenon is B called deshielding. In this example, the b. field is applied perpendicular to the plane of the molecule. The ring current is traveling clockwise if you look down at the plane THNMR YANIn some cases, such as the benzene molecule, the circulation of the electrons in the aromatic orbitals creates a magnetic field at the hydrogen nuclei which enhances the Bo field.
