## Abstract Firstβorder phase transitions are modelled by a nonβhomogeneous, timeβdependent scalarβvalued order parameter or phase field. The time dependence of the order parameter is viewed as arising from a balance law of the structure order. The gross motion is disregarded and hence the body is
Raman and IR studies of a single orthorhombic crystal and of polycrystalline trigonal RbIn(MoO 4 ) 2 were performed at ambient temperature. The observed vibrational modes were assigned to the respective motions of atoms in the unit cells. It was shown that the first-order D 3d 3 β D 2h 16 phase tran
