The far-ultraviolet spectra of the series of fluorine-substituted ethytenes were measured between 2000 and 1lSOk The main features of the spectra are a 8+ -n band whose peculiar shifting is discussed. a band which seems to be analogous to the @-?r "mystery band" of oiefins and Rydberg series.

β¦ Synopsis
The far ultraviolet spectra of gaseous isobutane, isopentane and neopentane were measured up to 1150 angstroms.
They are compared to the related normal isomer in each case. A tentative interpretation of the spectra is given. In previous papers from this Laboratory the electronic spectra of gaseous normal alkanes from methane to octane [l], [2] were presented. In this paper, we report on the spectra of isobutane, isopentane and neopentane. The spectra were measured with a McPherson model 225 vacuum spectrophotometer under 0.2
