Neptunium dioxide and tetrafluoride are converted in essentially quantitative yield to volatile neptunium hexafluoride by dioxygen difluoride (O2F2), both in gas–solid reactions at ambient temperatures and in liquid anhydrous hydrogen fluoride at

The gas phase electronic absorption spectra of CrO2F2 and CrO2Cl2 have been measured in the visible, near ultraviolet regions. Interpretation has been made by comparison with a molecular orbital calculation for each molecule by the SCF‐Xα‐SW met

Chlorine pentafluoride has been prepared successfully in high purity by the fluorination of ClF 3 at −78°C with dioxygen difluoride. The yield of ClF 5 by this method is quantitative. The procedure illustrates the general utility of O 2 F 2 in hig

Complex vibronic structure has been observed in the electric‐dipole‐forbidden charge transfer absorption bands of solid and matrix‐isolated UF6 in the temperature range 8–14 K. These bands have their maximum intensity near 260 and 375 nm. Ass

The infrared-active stretching fundamental ν3 of WF6 vapor has been studied over the temperature range T = 190–310 K. At lower temperatures the hot-band structure is sufficiently suppressed to allow accurate measurements of the P-R branch spacing,

A total of 44 bands in the infrared and Raman spectra of 238UF6 vapor has been measured using long‐path absorption cells and multiple‐reflection Raman cells. The types of contours exhibited by these bands, and analogous contours in the spectrum o

Infrared spectra of W35Cl6 and W37Cl6, prepared from 99.4% 35Cl and 90.4% 37Cl respectively, were recorded in CCl4 and CS2 solutions. The isotope shifts in the F1u fundamentals ν3 and ν4 were used to determine the general quadratic symmetry force c
