Abstract
The neat and mixed crystal emission spectra of UF6 are analyzed. It is found that long uniquantal progressions appear in the ν5 (t2g) vibration built on the origin, ν6 (t2u), and n1ν1 (a1g). The maximum intensity in all these series falls around n5=2. These data are interpreted as being indicative of a substantial molecular Jahn–Teller interaction in the excited charge transfer state. Using a modified Franck–Condon analysis for a three-dimensional vibrational space, it is found that D5 ∼2.02 and that the excited state is distorted along each of three ν5 coordinates by roughly 0.09 Å.Keywords
