 Title: THE VACUUM ULTRAVIOLET ABSORPTION SPECTRA OF SOME ETHERS$^{\ast}$ Creators: Hernandez, G. J. Issue Date: 1962 Publisher: Ohio State University Abstract: The electronic absorption spectra of some ethers were investigated with a Hilger 2 meter normal incidence vacuum spectrograph with a conventional hydrogen discharge and the rare gases continua as background. The absorption spectra of the ethers investigated show certain similarities which are ascribed to the presence of oxygen in the molecular framework. The most outstanding similarity is a very strong absorption in the region $51,000 cm^{-1}$ to $58,000 cm^{-1}$. Analysis of the above mentioned and higher frequency absorption regions shows that the levels predominantly excited are those associated with vibrational modes of the molecular framework in which the oxygens take part. This lends support to the localization of the transitions to the non-bonding electrons of the oxygen common to the ethers. For those ethers that show Rydberg series, the determined ionization potential compares well with those determined by electron impact and/or photoionization techniques.
