Abstract
To estimate the 19F chemical shifts of substituted 6-ring heteroaromatics, the same increments, Zi, can be used as for substituted fluorobenzenes (see preceding page). However, different base values, Y (as given below), apply depending on the number and position of nitrogens and the position of the fluorine substituent in question.
