19F NMR Chemical Shifts and Coupling ConstantsTable of Chemical Shift Ranges
Chemical Shift Table For certain compounds, the listed chemical shift pertains to the F shown in bold. The primary references for these values are: 1) the 1991 Bruker Almanac, and 2) Compilation of reported F19 NMR chemical shifts, 1951 to mid-1967 by Claude H. Dungan and John R. Van Wazer. Negative shifts are those that appear upfield of CFCl3 and positive shifts are those that appear downfield.
Homonuclear CouplingsListed Coupling constant values pertain to Fs shown in bold.
