✦ Synopsis

The infrared and Raman spectra of polycrystalline were recorded at 77 and 10 K, respectively. (CH 3 ) 3 CCCH Crystal splittings were observed for some of the fundamentals and possible crystal structures are discussed. Anomalous band shifts between the liquid and solid state spectra were noted for butyne yCH modes, indicating that a strong intermolecular interaction involving the butyne CH group occurs in the crystalline state. The temperature dependence of the Raman spectra was measured for some prominent fundamental bands. No phase changes were detected. In the solid-state Raman spectrum, bands attributable to both and E methyl torsions were observed.

The low-temperature form of K 3 Sm(PO 4 ) 2 crystallizes in the glaserite type. The Raman and infrared spectra have been investigated: they are consistent with the proposed space monoclinic system [a = 7.4347(5) A ˚, b = 5.6270(5) A ˚, c = 9.4919(5) A ˚, β = 90.870(6)°, Z = 2, space group P2 1 /m].
