Abstract: |
An expression of electron ring currents of molecule in the presence of a uniform external magnetic field is derived upon the basis of the quantum theory with gauge invariance. A general formulation for magnetic susceptibility is obtained. The susceptibility of C60 and C70 is calculated by using the theory. The quantum ring current theory is compared with the London rign current theory, and the approximation in the London theory is pointed out. |
