โฆ Synopsis
We prove that the lowest order contributions to the high frequency optical activity of any system is non-zero only if there are two or more electrons in the system.

The coupled-dipole method is extended to include intrinsic optical activity in the material of an arbitrarily shaped particle. The dipolar subunits used in the method are spherical or ellipsoidal. Good agreement is obtained on comparison with the exact theory for an optically active sphere.
