The effect of temperature on the Raman spectra of natural and synthetic chondrodite was investigated over the range 81 to 873 K at atmospheric pressure. All samples remained intact up to 873 K. This hightemperature stability is unusual, and contrasts with the behaviour of all other synthetic dense h
Micro-Raman spectra measurements in the wavenumber region 20-900 cm-1 reveal a complex temperature dependence of the Raman phonon modes on cooling ceramics down to 70 K. An anomalous line narrow-Bi 2 Ti 4 O 11 ing behavior of some phonon modes is observed and is associated with ordered distributions
A collision model for thevibrational relaxation of hydrogen fluoride at low temperatures is proposed. Because of the contribution of a strong hydrogen-bond attraction, the molecules are considered to undergo oscillatory motion about their equitibrium orientations This motion is taken to be primarily
The Raman-active lattice modes in quartz-homeotypic crystal at low and room temperature were investi-GaPO 4 gated using a Raman spectrometer of limiting resolution 0.005 cm-1. Particular attention was paid to the comparison of the LO-TO splittings of the low-lying energy E modes in the series and Th
