the hydrolysis of XeF4and XeF6readily gives the explosive, isolable (at one's risk) xenon trioxide and xenon tetraoxide. Interestingly, the equally sensible xenon monoxide and dioxide remain uncharacterized and all but unknown and unstudied, a situation reminiscent of the valence isoelectronicoxyanions...

Nuclear magnetic resonance (NMR) of hyperpolarized xenon-129 (HP129Xe) atoms has been widely used in a variety of research areas, such as physics, chemistry, material science, and biomedical imaging1,2. HP129Xe gas is usually produced via a spin-exchange optical-pumping (SEOP) method, in ...
The magnetic signal of 129Xe can be increased by several orders of magnitude by spin exchange optical pumping (SEOP), a method that uses circularly polarized light to excite the valence electrons of rubidium which then, in turn, collide with Xe in the gas state and polarizes the Xe nuclei...
Experimental evidence is consistent with a distorted octahedral structure for gaseous XeF6 arising from the presence of an extra pair of nonbonding electrons in the xenon valence shell. Solid XeF6 exists in at least four phases which consist of tetrameric and hexameric rings of virtually undistorted...
(XeF4) is a square planar molecule, and XeF6in the gasphaseis a distorted octahedral molecule arising from the presence of an “extra” pair of nonbondingelectronsin the xenonvalenceshell. Higher halides such as XeCl2, XeClF, XeBr2, and XeCl4are thermodynamically unstable and have been ...
