Abstract

High resolution mass spectra of compounds 1—8 were investigated. For the quinolines (1–3) the absence of major peaks other than M+ and (M-1)+ reflects the stability of those systems. The N-oxides (4–6) all exhibit major peaks at M+, (M-16)+, and (M-17)+. In addition, 4 shows prominent fragmentations reflecting loss of hydrogen and carbon monoxide. The pathways are related to the geometries of the N-oxides; deuterated compounds (7–8) aided these assignments.

Abstract

Xenon tetrafluoride reacts with water to yield xenon, oxygen, hydrofluoric acid, and a very soluble species containing xenon. Evaporation of the solution yields a white, crystal-line substance which has been identified as xenon (VI) oxide, XeO(3).

Abstract

Sodidm perxenate hexahydrate ( NatXeO6.6H: O) has been identified from study of its crystal structure by x-ray diffraclion. The perxenate ion( XeO64) has the shape of a regular octahedron with the Xe-O bond distance 1.84 A.
