Abstract
A Landau theory of the smectic transition at constant volume is proposed. The coupling constants of this theory are then derived from a previously published microscopic theory. Coupling between the orientational order and the lattice-strain tensor is then introduced, and it is shown that this causes the transition to be first order. Elastic neutron scattering is discussed as an experimental test of the microscopic theory. Finally, interlayer interactions are included.
