The fluorine chemical shifts and spin-spin coupling constants of 65 pentafluorophenyl derivatives with widely varying organic substituents were examined. Useful correlations of the three meta coupling constants with the chemical shifts of thepara fluorine were found. It is suggested that these relat
## Abstract Chemical shifts and coupling constants are reported for a series of the title compounds and the effects of substituents on these values correlated with the corresponding effects in benzenes. Partial bond fixation in these and other benzoβheterocycles is discussed together with the gener
