Redox controls on H and N speciation and intermolecular isotopic fractionations in aqueous fluids at high pressure and high temperature: Insights from in-situ experiments
Autor: Celia Dalou, Charles Le Losq, Evelyn Füri, Marie-Camille Caumon
Publikováno v: Frontiers in Earth Science, Vol 10 (2022)
Aqueous magmatic fluids are essential to the transport of hydrogen (H), carbon (C), and nitrogen (N) from the mantle to the surface, during which changes in pressure, temperature, and redox conditions affect the chemical speciation and intermolecular

Interpretation of the pressure-induced Raman frequency shift of the ν1 stretching bands of CH4 and N2 within CH4–CO2, N2–CO2 and CH4–N2 binary mixtures
Autor: Van-Hoan Le, Alexandre Tarantola, Marie-Camille Caumon
Publikováno v: Physical Chemistry Chemical Physics
Physical Chemistry Chemical Physics, Royal Society of Chemistry, 2021, ⟨10.1039/d1cp00163a⟩
The relationships between the frequency shift of the ν1 stretching bands of CH4 and N2 with pressure (or density) and composition have been previously provided in the literature as reliable parameters for accurate empirical barometers and densimeter
