## Abstract Thermodynamic p__K__~a~โ€values have been determined for 38 4โ€substituted quinuclidinium perchlorates. They are remarkably sensitive to the polar effect of the substituent and cover a range of 3.63 p__K__~a~ units. Furthermore, they vary linearly and almost equally with temperature since
