13C NMR chemical shifts were measured in for Γuorocarbonyl compounds. Sulfonic DMSO-d 6 derivatives display 4J(C,F) coupling constants for carbonyl groups which are also obtained from non-sulfonic derivatives when they are recorded in acidic solution.
The "C chemical shifts of 22 methylated ribonucleosides and deoxyribonucleosides have been measured and assigned. The chemical s h i f t ditierences between methylated and unmodified nucleosides are correlated with their characteristic modifications of structure. The significance of the chemical shi
