Abstract
The 70 eV mass spectra of unsubstituted cyclic polyethers, “crown ethers”, from 12-crown-4 (12 membered ring) to 21-crown-7 (21 membered ring) are reported. These compounds exhibit very nearly identical spectra. Preferred secondary structures for these compounds from solution studies are used to explain specific unimolecular rearrangements; that is, the mass spectra of these “three dimensional molecules” is discussed.
