Longhyphen;Wavelength, Infraredhyphen;Active Fundamental for Uranium, Neptunium, and Plutonium Hexafluorides

摘要

The longhyphen;wavelength, infraredhyphen;active fundamentals, ngr;4, have been observed for uranium, neptunium, and plutonium hexafluorides at 186.2, 198.6, and 206.0 cmminus;1, respectively. The corresponding values predicted earlier from combination bands were 184, 198, and 203 cmminus;1. From thePmdash;Rbranch separations Coriolis zeta constants have been calculated for these bands.
