...%) and Ar/H 2(10%) at ambient pressure between 400 and 700 °C. FTIR analyses were performed before and after each annealing run. Between 15 and 35% of the original OH content remained in the crystal structure at the end of the deuteration experiments. This contrasts with the results of similar experiments...

...Kiyotaka Ishida; Frank C. Hawthorne Abstract Infrared OH-stretching bands of calcic amphiboles in the magnesiohornblende-tschermakite/ferrotschermakite and edenite-pargasite/hastingsite series have been assigned by deuteration and heat treatment in air. Mössbauer spectra indicate...

...HUI MING Abstract Kaolinites were modified by controlled hydrothermal deuteration. Both infrared and near infrared vibration spectra of deuterated kaolinite were investigated by Diffuse Reflectance Infrared Fourier Transform spectroscopy. The stretching vibrations (ν) of deuteroxyl groups...

.... In contrast to the Dora Maira pyrope, for the two pyrope crystals extracted from xenoliths, the total concentration of hydrous species is not preserved during H-D exchange experiments; dehydration occurs concurrently with deuteration. This renders the analysis of the kinetics of H-D exchange difficult...

...William J. Furbish Abstract Corrensite occurs as the result of deuteric action in a sill-like gabbro body near Durham, North Carolina. It forms both as a replacement product of chlorite in chlorite-prehnite or chlorite-laumontite alternation zones in the gabbro and as a hydrothermal fracture...

...Anastasios Antonakos; Efthymios Liarokapis; Andreas Kyriacou; Theodora Leventouri Abstract We have studied synthetic Fe-substituted hydroxyapatite Ca 5−x Fe x (PO 4 ) 3 OH and the corresponding deuterated samples with varying Fe concentrations x (0 ≤ x ≤ 0.3) by Raman and IR spectroscopy at room...

... and pressures up to 7 MPa. The samples were prepared from mixtures of ground, deuterated ice and deuterated methanol (up to 20 vol%), which were transformed in situ into CO 2 - or CH 4 -hydrates by pressurizing the systems with the corresponding gas. The observed rates of formation of hydrates are orders...
