Changes in chemical shifts of olefinic protons in a number of a$-and a,P,y,G-unsaturated carboxylic acids caused by ionization of the COOH group were investigated. The ionization shifts of a-H-atoms are -0.09 to 0.07 ppm, those ofg-H-atoms are 0.324.47 ppm. The ionization shifts of 8-H-atoms are sub
