The dynamic behaviour of CH4-H2O solutions
In the proposed experiment both the rotational and transitional dynamics of the molecules in CH4- H2O mixtures will be studied. This will be achieved by selectively deuterating the mixture, such that the CH4 and H2O dynamics may be studied separately. Measurements will be carried out at multiple pressures, both above and below the proposed change in hydrophobicity at 1.5 GPa. Our results will be compared to existing QENS studies of CH4 and H2O [7, 8], in order to establish if there are any effects due to mixing on the individual components. We will track the diffusive behaviour with pressure, with the aim of determining any links between the molecular motions and the CH4 solubility.
