| Abstract: | Magnetic field induced spatial dispersion of the dielectric permeability is discussed for a crystal possessing a Td symmetry. Bilinear terms of the ground state exciton hamiltonian are obtained using the method of invariants. Relevant material constants are expressed in terms of the band parameters. |
