Abstract
p__K__~a~ Values of 42 quinuclidinium perchlorates I have been measured in 0.1 M aqueous KCl‐solution. In a few cases small corrections of earlier thermodynamic p__K__~a~ values are indicated. These measurements, in conjunction with recent X‐ray structure determinations, confirm the reliability of the inductive substituent constants σ~I~^q^ derived from them.
