Laboratory and synchrotron X-ray powder di4raction and neutron powder di4raction have been used to determine crystal structures in the perovskites SrTi x Zr 1Ψx O 3 . Superlattice re6ections in the neutron di4raction patterns proved to be the most reliable indicators of lower symmetry structures. Th
R;unan and infrared spectra of pol~uystaIIine samples of bromoform and deuterated bromoform in the temperature range 20-274 I; are reported. Spectra in both the lattice and intramotecular regions are compared with earlier results and interpreted in temls of the known structures of the three phases o
Neutron powder diffraction patterns were measured for the ordered a-phase and the disordered b-phase of deuterated methanol. The structure of the a-phase at 160 K is in agreement with that found earlier at 15 K. A complete refinement of the structure of the b-phase at 170 K was also carried out. The
