The liquid caesium-oxygen system in the metallic regime has been investigated by the NMR technique. Measurements were made of the Knight shift for both Cs-133 and O-17 nuclei, and the nuclear relaxation time, T1, for the latter. The Knight shift for Cs-133 nuclei decreases almost linearly up to 25 at.% of O and further decreases with a steeper slope to the value in Cs2O, while the shift for O-17 nuclei is almost independent of the composition up to 21 at.%. The analysis of T1 suggests that the gradient of the electrostatic field coupled with the nuclear quadrupole moment of O-17 is also insensitive to the composition. The results are discussed with particular reference to the state of the 0 atoms and possible ionic association in the liquid Cs-O system in the metallic regime.
