Absorption spectra of UF/sub 6/ dissolved in liquid xenon, krypton, nitrous oxide, and methane have been obtained between 300 and 500 nm and between 400 and 4000 cm/sup -1/. Eighteen infrared bands of UF/sub 6/ were observed and were moderately (2--9 cm/sup -1/ FWHM) narrow. The band positions were found to move toward higher wave numbers nu-tilde as the temperature T was increased; dnu-tilde/dTapprox.0.02 cm/sup -1///sup 0/C for the bands examined. Some anharmonicity constants were determined and were within experimental error of previous values for UF/sub 6/ vapor. Integrated absorption cross sections for the ..nu../sub 3/, ..nu../sub 5/+..nu../sub 3/, ..nu../sub 2/+..nu../sub 3/, and ..nu../sub 1/+..nu../sub 3/ bands of UF/sub 6/ were measured to be roughly-equal1 x 10/sup -16/, 1.8 x 10/sup -19/, 5.8 x 10/sup -19/, and 3.9 x 10/sup -19/ cm/sup 2/--cm/sup -1/, respectively. The solubilities of UF/sub 6/ in liquid xenon, krypton, and methane have been measured.
