✦ Synopsis

The general formal expression for the wavevector-and frequency-dependent dielectric susceptibility tensor of a simple molecular crystal, derived in paper 1, is applied to the case of a Bravais lattice with gyrotropic molecules. The dielectric susceptibility tensor is calculated with first-order spatial dispersion and from this an expression for the gyration tensor is derived. As an example the optical rotatory power is calculated for light propagating along the optical axis of a gyrotropic tetragonal crystal. * In paper I the r.h.s, of the eqs. (I.2.18), (I.2.19), (I.A.oO and (I.A.I 1) should be multiplied with a factor (2~z) 3 and the r.h.s, of eq. (I.A.7) with a factor (2z0 6.
