The relation between the fluorine hyperfine splittings in about 20 fluorine substituted aromatic radicals and the π spin densities calculated according to McLachlans method is analysed with an expression of the type

aF = QFFF ρπFF + QFCC ρπCC + (QFFC + QFFC) ρπFC .

For the Q factors the following values are obtained:

QFFF =931 gauss; QFCC =86.6 gauss and (QFFC + QFFC) =345 gauss.

Two simpler expressions with one and two parameters respectively are also tested.

A theoretical estimate is made for the values of the Q factors and the results are compared with the values obtained semi-empirically.
