The Absorption Spectrum of UF6, from 2000 to 4200 Å

The absorption spectrum of UF6 between 3400 and 4200 Å, is well-documented,(1–3) but the region below 3400 Å has not been studied in any detail. We present here a spectrum of UF6 between 2000 and 4200 Å that shows significant structure below 3400 Å. The absorption in this region must be observed at very low pressures and relatively short path lengths.
