The case of methoxyflurane (CHjOCFjCHCl ) is similar (Fig. 9). The four Cl IPs are resolved at 11.5, 12.2, 12.4 and 13.2 eV. Comparison with the spectrum of CFj—CHClj shows that the methoxy group has a lowering effect on these IPs. It is of some interest to search for the photoelectron band which corresponds to ionization from the essentially oxygen lone pair orbital (O). Hardin and Sandorfy identified this band near 14 eV in fluoroethers and there is no reason to expect it at much lower energies for methoxyflurane. This is even more so for enflurane in which both neighbours of the oxygen atom are fluorinated. 

The lowest bands of enflurane (CF HOCF CHFCl) are at 12.2 (shoulder) and 12.6 eV. Clearly they correlate to the chlorine lone pair whose energy is split due to the lack of symmetry in this molecule (Fig. 10).
