## Abstract The ^1^H and ^19^F spectra of a variety of mono‐ and di‐ fluorinated pyridines are examined, and compared with the corresponding spectra of the pyridinium ions. The magnitudes and signs of the ^1^H^19^F coupling constants are in general in accord with those observed for the correspondi

Abstract
The mass spectra of some deoxyfluorohexopyranose acetates bearing the fluorine substituent at positions 2,3,4, or 6 were determind. The fragmentation pathways were analogous with those for hexopyranose acetates, except that the cleavage of bonds between carbon atoms was hindered by the attachment of a fluorine substituent to one of the carbon atoms.

The most prominent ion in the mass spectra of C,F,CH,X (X = H, Br, CH:CH,, COCI, and CH,C6F5) is C,F5H2+, formulated as the pentafluorotropylium cation. This ion is also found, in an amount comparable to the parent ion, in the spectrum of (CBF5)\*CH2. The heptafluorotropylium cation is found similar
