WebDouble bond. In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond. Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom … WebIn the electronic and torsional and rotational ground state of toluene, the strengths of the diatropic and paratropic nuclear… Show more We develop the theory of nuclear ring currents induced by external magnetic fields in torsional molecules. The theory is applied to toluene, whose torsion axis is oriented along the magnetic field.
